- What should you check before buying a Craftsman bleed valve?
- How do you choose the best Craftsman air compressor bleed valve?
The best Craftsman air compressor bleed valve for most tank-drain repairs is the Hromee 5 Piece 1/4 Inch Compressor Air because it includes a 1/4 in NPT drain cock, petcock, safety valve and plugs. That mix suits owners who find more than one worn tank port at the same time.
Choose the Craftsman A19712 when you need a compatible check-valve replacement for a listed Craftsman model. It solves a different job from a tank drain, so the compressor model and original part number matter more than the thread size alone.
A Craftsman compressor can have several parts that release or control pressure. The tank drain removes moisture that collects at the bottom of the receiver, a relief valve lets you reduce pressure in a tire or line in a controlled way, and a safety valve protects against excessive tank pressure.
Check the port before you order. Many picks here use 1/4 in NPT connections, but the Craftsman A19712 uses compression connections and is a check valve rather than a tank drain.
Thread size alone is not enough to confirm fit. Valve style, clearance around the tank, the pressure rating and the job the part has to do all affect whether a replacement will work in daily use.
A simple drain cock is often best when the outlet is easy to reach and the port match is clear. An extended drain or a multi-piece kit makes more sense when access is poor or several small fittings need attention.

Which Craftsman air compressor bleed valve is best for your repair?
The best choice depends on whether you are draining tank moisture, replacing a model-specific part, or bleeding pressure from a tire. The Hromee kit is the broadest tank-port option, while the Craftsman A19712 is the most targeted Craftsman replacement.
We compared the stated thread types, valve functions, included parts, and model references. Our score weighs specs, features, and buyer feedback against the needs of someone matching a Craftsman compressor part.
Start with the job, not the brand name on the box. A drain cock, a check valve, a safety valve, and a regulator knob may all sit on the same compressor, but they do not swap places with each other.
That first decision saves time and money. If water collects at the bottom of the receiver, you need a drain valve or petcock.
If the pump line is the problem, a tank drain will not solve it.
Then check the connection and the space around it. A 1/4 in NPT part can only fit a matching female port, while compression fittings and model-specific parts need a closer match.
Look closely at the old part before you order. Note the thread size, the shape of the handle, and whether the part screws into the tank or connects to a line.
A photo of the label can help you confirm the model later.
Consider clearance as well as thread size. A valve may fit the port but still be hard to turn if a frame rail, floor, or hose sits too close.
That small detail affects whether you will actually use it every week.
For routine care, ease of use matters as much as the spec sheet. A valve that is awkward to reach may get skipped, and skipped drainage lets moisture build up inside the tank over time.
Moisture left in the tank can encourage rust and carry water into tools or paint work. A drain that you can open quickly after a run is more likely to become part of your normal routine.
Think about setup too. Some repairs need only a direct drain cock, while others need a hose to move the control point.
The right choice depends on your compressor layout, not on which part has the longest feature list.
If you have more than one compressor, check each port on its own. Two units may look alike yet use different openings or valve styles.
Matching each one by hand avoids a return and a second wait for the correct part.
It also helps to separate small jobs from larger ones. A spare knob, a safety valve, and a drain cock each fix a different fault, even when they appear in the same roundup.
By the time you compare prices or pack sizes, narrow the list to parts that do the right job and fit the right port. That order of checks leads to a more useful repair and a compressor that is easier to maintain.

1. Hromee 5 Piece 1/4 Inch Compressor Air: Best for complete tank-port repairs
Hromee 5 Piece 1/4 Inch Compressor Air: Best for complete tank-port repairs
- 1/4 in NPT drain cock
- Twist-style petcock
- 140 PSI safety valve
- 5-piece brass fitting set
This set covers several common tank-port needs with a wing-style drain cock, twist-style petcock, safety valve and hex-head plugs.
Pros
- Includes drain and safety components
- 1/4 in NPT fittings
- Brass construction
Cons
- May include parts you do not need
- Thread sealant is recommended
The Hromee 5 Piece 1/4 Inch Compressor Air is the best all-around match when you need more than a single drain cock. The set includes a 1/4 in brass wing-style drain cock, a twist-style petcock, a 140 PSI safety valve and hex-head plugs.
The wing-style drain cock is intended for moisture drainage from air compressor tanks. The twist-style petcock uses a knurled grip and an O-ring seal for opening and closing the drain.
The safety valve has a brass body, stainless steel spring and pull ring, with a maximum pressure of 140 PSI and airflow of 55 SCFM. Use its stated pressure rating as a matching point, not as permission to change your compressor's safety settings.
This kit is a strong fit when you want common tank-port pieces in one package. Check the existing port and use thread sealant as directed for brass fittings.
2. Hromee Extended Tank Drain Assembly Kit: Best for easier daily draining
Hromee Extended Tank Drain Assembly Kit: Best for easier daily draining
- 10 in braided steel hose
- 1/4 in drain valve
- Elbow fitting
- Thread seal tape
The extended hose moves the drain control away from the tank, making routine moisture drainage easier to reach.
Pros
- Extended drain position
- Braided hose resists kinks
- Includes elbow and tape
Cons
- Check available clearance first
- Not a model-specific Craftsman part
The Hromee Extended Tank Drain Assembly Kit is the best choice when the tank drain is difficult to reach. Its 10 in braided steel hose moves the valve away from the bottom of the tank and includes a 1/4 in ball valve, elbow fitting and thread seal tape.
The hose is designed to resist breaking and kinks. That flexibility helps on units where a rigid fitting would point the handle into the floor, a frame rail or another obstruction.
The assembly has a stated maximum working pressure of 175 PSI, while the ball valve has a separate pressure rating of 300 PSI at its maximum operating temperature. Treat those as two limits for two parts, and keep the lower assembly figure in mind for the whole setup.
A remote drain can make routine maintenance less awkward, but it also adds length and fittings. Measure the space below the tank and make sure the hose can hang without sharp bends.
Route the hose away from hot surfaces and edges that could rub against it during use. A gentle curve keeps the braided hose working as intended and avoids stress on the threaded joints.
Use this pick when the main problem is access. If the drain outlet is already easy to reach, a simple replacement cock may be all you need.
3. Kbrotech Extended Tank Drain Valve Assembly Kit: Best for a longer flexible drain
Kbrotech Extended Tank Drain Valve Assembly Kit: Best for a longer flexible drain
- 15 in braided steel tube
- Quarter-turn drain valve
- Pre-applied thread sealant
- 3/8 in to 1/4 in adapter
This assembly gives you a longer flexible route from the tank drain to a more accessible valve position.
Pros
- Longest hose in this roundup
- Quarter-turn valve
- Includes adapter and tape
Cons
- Needs room for the longer assembly
- Model fit depends on the tank port
The Kbrotech Extended Tank Drain Valve Assembly Kit gives you the longest hose in this roundup, with a 15 in braided steel tube and an overall length of about 17 in. It also includes a quarter-turn drain valve, adapter and thread seal tape.
The assembly uses 1/4 in NPT pipe fittings and includes a 3/8 in male NPT to 1/4 in female NPT hex bushing. That adapter helps when the tank port and the drain route do not share the same diameter.
The valve has a stated maximum pressure of 300 PSI. Check that rating against the pressure your compressor actually reaches before fitting the assembly.
This option suits a compressor where the tank drain sits close to the floor, a frame member or another obstruction. The extra reach can turn a cramped daily task into a simple quarter turn.
The longer tube may be less suitable when the compressor has little clearance around the tank. Plan the route first so the tube does not kink, rub or pull on the fittings.
Choose it when reach matters more than compact size. Confirm the original drain connection and plan the hose route before installation.
4. Campbell Hausfeld 1/4" NPT Air Compressor Drain: Best for a simple 1/4 in NPT replacement
Campbell Hausfeld 1/4" NPT Air Compressor Drain: Best for a simple 1/4 in NPT replacement
- 1/4-18 NPT male connection
- Brass drain cock
- Replaces D-1403
- Single-valve replacement
This single brass valve suits compatible compressor tanks with a matching 1/4 in NPT drain opening.
Pros
- Simple replacement format
- Brass construction
- Clear replacement part reference
Cons
- Designed around compatible drain openings
- Confirm your compressor model first
The Campbell Hausfeld 1/4" NPT Air Compressor Drain is the cleanest choice for a compatible tank with a 1/4-18 NPT drain opening. It is a single brass drain cock that replaces the Campbell Hausfeld D-1403 valve.
This replacement is intended for compatible Campbell Hausfeld single-stage compressors, select two-stage models and some other compressors with the same opening. Its model reference is GR001400AJ.
Although the brand name is different from Craftsman, the 1/4 in NPT connection may suit some compressor tanks. Match the original valve, port and parts diagram rather than choosing by brand alone.
Brass construction suits a part that will see moisture at the lowest point of the tank. It is a simple, direct format for owners who only need the worn drain renewed.
Pick it when you want one basic drain valve. It does not include a hose, elbow or spare valve, so it will not help if reach is the main issue.
Depressurize the tank fully before removing the old valve. Then seal and fit the replacement according to the compressor instructions and check for leaks before returning the unit to service.
5. Craftsman A19712 Check Valve for 919.167342: Best for listed Craftsman model repairs
Craftsman A19712 Check Valve for 919.167342: Best for listed Craftsman model repairs
- Replaces AC-0631
- Fits listed Craftsman models
- Compression connections
- Metal construction
This is a model-focused replacement for listed Craftsman compressors, including 919.167342 and several related models.
Pros
- Craftsman model compatibility list
- Replaces AC-0631
- Useful for check-valve repairs
Cons
- Not a tank drain cock
- Verify model and compression sizes
The Craftsman A19712 is the best targeted option for a listed Craftsman compressor with a failed check valve. It replaces part number AC-0631 and is compatible with models including 919.167342, 919.165610 and 919.167320.
This is not a tank drain cock. It is a model-specific check-valve replacement with compression connections, so the repair depends on matching the compressor model and the original fitting arrangement.
For repair parts, compare air compressor check valve repair kits.
The compatibility list also includes several 919-series Craftsman models. Compare the exact model number on your compressor before ordering because a similar-looking valve may use different connections.
For another brand, see Ingersoll Rand compressor check valves.
Choose this part when your repair calls for A19712 or AC-0631. For routine moisture drainage, use a tank drain valve instead.
6. Otoolling 2 Pcs Brass Air Tank Drain: Best for keeping a spare drain valve
Otoolling 2 Pcs Brass Air Tank Drain: Best for keeping a spare drain valve
- 2 brass drain valves
- 1/4 in NPT male threads
- 200 PSI WOG maximum working pressure
- Air tank drainage use
The 2-piece pack gives you a replacement valve and a spare for compatible 1/4 in NPT tank ports.
Pros
- Two valves in one pack
- Brass construction
- Common 1/4 in NPT format
Cons
- No extended hose
- Confirm pressure and thread needs
The Otoolling 2 Pcs Brass Air Tank Drain is useful when you want one compatible valve installed and another kept as a spare. Both valves use 1/4 in NPT male threads and are made for air tank drainage.
The valves have a stated maximum working pressure of 200 PSI WOG. Check that figure against your compressor pressure before treating the pack as a direct fit.
Their compact format does not add a hose or remote handle, so check whether you can reach the tank outlet comfortably. On a low outlet, opening the valve may still mean crouching or working by feel.
This pack works best for a basic replacement or a workshop that maintains more than one compatible compressor. A spare is handy because drain cocks can wear, leak or seize with age.
It is less useful when you need an extended drain assembly or a model-specific part. Confirm that your Craftsman tank uses a 1/4 in NPT female opening before choosing it.
7. Toobop 137-0001 Manifold Plastic Air Compressor Regulator: Best for a regulator knob replacement
Toobop 137-0001 Manifold Plastic Air Compressor Regulator: Best for a regulator knob replacement
- 137-0001 replacement knob
- Fits Sanborn, Craftsman and Coleman units
- Includes 055-0005 spring
- ABS construction
This part addresses a broken regulator knob or spring on compatible Sanborn, Craftsman, Coleman PowerMate and Industrial Air compressors.
Pros
- Specific replacement reference
- Includes spring
- Fits several named brands
Cons
- Not a bleed or tank-drain valve
- Confirm the original knob number
The Toobop 137-0001 Manifold Plastic Air Compressor Regulator is included for a different Craftsman repair. It replaces a 137-0001 regulator knob and comes with the 055-0005 spring.
The replacement is intended for compatible Sanborn, Craftsman, Coleman PowerMate, and Industrial Air compressors. It uses female threads of about 1 1/4 in and is made from ABS.
A regulator knob controls adjustment at the manifold. It does not drain tank moisture or replace a safety valve, check valve, or petcock.
This distinction matters because a broken knob can look like a pressure problem while the tank drain is untouched. Replacing the knob will not clear water from the receiver or stop a leaking drain cock.
The included spring is part of the small hardware around the knob, so inspect the old spring for wear before you decide whether to fit the new one. If the spring is bent, weak, or missing, the knob may not sit or turn as it should.
Choose it only when the original knob reference matches 137-0001. Check the old part and compressor brand before ordering, and confirm whether the spring also needs renewal.
8. CRAFTSMAN Inflator Gun: Best for bleeding tire pressure
CRAFTSMAN Inflator Gun: Best for bleeding tire pressure
- 0 to 150 PSI gauge
- Air chuck and relief valve
- 12 in inflation hose
- 1/4 in NPS male threads
This inflator gun controls tire pressure rather than draining an air-compressor tank. Its relief valve lets you bleed excess air without removing the chuck.
Pros
- Built-in gauge
- Relief valve for tire pressure
- Includes several inflation attachments
Cons
- Not a tank drain replacement
- Female quick-connect plug is not included
The CRAFTSMAN Inflator Gun is the best pick here for bleeding excess air from tires or other inflation jobs. It combines an air chuck, trigger handle, 0 to 150 PSI gauge and relief valve.
The 12 in poly hybrid hose stays flexible in cold temperatures, and the clip-on chuck supports one-handed use. That short hose keeps the tool close to the valve stem, which helps when you are working at tire height.
The tool also includes attachments for sports balls, air mattresses, dusting and cleaning. Those extras make it a general inflation tool rather than a single-purpose tire gauge.
Its relief valve lets you reduce tire pressure without disconnecting the chuck. That makes it a pressure-control tool, not a replacement for the drain valve at the bottom of a Craftsman compressor tank.
Choose it when “bleed valve” means controlled tire deflation. For tank moisture, choose one of the drain cock or extended drain assemblies above.
9. TAISHER 5PCS Brass Drain Cock Ball Valve: Best for multiple basic drain replacements
TAISHER 5PCS Brass Drain Cock Ball Valve: Best for multiple basic drain replacements
- 5 brass drain valves
- 1/4 in NPT male threads
- Quarter-turn operation
- 150 PSI working pressure
This 5-piece pack suits repeated replacement work when your compressor tanks use compatible 1/4 in NPT drain ports.
Pros
- Five replacement valves
- Quarter-turn operation
- Brass construction
Cons
- No hose or adapter
- Confirm the pressure requirement
The TAISHER 5PCS Brass Drain Cock Ball Valve is a practical multi-pack for compatible tank ports that use 1/4 in NPT male threads. Each brass valve uses quarter-turn operation for opening and closing.
The valves have a stated 150 PSI working pressure and a temperature range from -65 F to 250 F. Those figures set the conditions the valve is meant for, so compare them with your compressor before fitting.
The pack is useful for repeated repairs, but it does not include an extended hose or adapter. It suits straightforward replacements where the outlet is already reachable.
Quarter-turn operation is quick in daily use once the valve is seated. Open it slowly during drainage, since moisture and air can leave the tank with force at the start.
Choose this set when you need several compact replacement drains. Check the pressure requirement and thread match before installation, since NPT size is a nominal pipe size rather than the outside diameter.
What should you check before buying a Craftsman bleed valve?
Check the compressor model, the original part number, the port thread and the valve's job before choosing a replacement. A 1/4 in NPT drain cock cannot replace a compression check valve just because both parts fit an air compressor.
Is the part a tank drain, check valve or safety valve?
A tank drain releases water and air from the lowest point of the receiver. A check valve controls flow into the tank and may connect to the pump or discharge line.
A safety valve releases excessive tank pressure when its set point is reached. It is a protection device, not a tool for routine drainage or for setting your own pressure limit.
The Hromee kit includes a safety valve and drain parts, while the Craftsman A19712 is a check-valve replacement. For a dedicated pressure-protection comparison, see Best Air Compressor Safety Valve.
Before buying, name the job in plain terms. Moisture at the bottom of the tank points to a drain cock or petcock, while trouble with the pump line points elsewhere.
Then confirm the connection. A 1/4 in NPT male thread fits only a matching female port, and compression connections need their own size check.
Does the thread match the Craftsman tank?
Many drain picks here use 1/4 in NPT male threads. That does not guarantee fit because your compressor may use a different opening, a different valve body or a compression fitting.
Remove no part until the tank is fully depressurized. Compare the original valve, manual or parts diagram with the replacement connection.
Would an extended drain make maintenance easier?
An extended drain helps when the tank outlet is low or difficult to reach. The Hromee assembly uses a 10 in hose, while Kbrotech uses a 15 in braided tube.
Measure the available space and keep the hose away from sharp edges and hot surfaces. A longer assembly is useful only if it can be routed without kinks or strain.
Is an unloader valve part of the same repair?
Usually not. An unloader valve releases pressure from the pump discharge line when the compressor stops, which helps the motor restart.
Read What Does The Unloader Valve Do On An Air Compressor? and What Is an Air Compressor Unloader Valve? before replacing a part described as an unloader.
How do you choose the best Craftsman air compressor bleed valve?
Choose the Hromee 5 Piece 1/4 Inch Compressor Air for the broadest tank-port repair kit. Pick the Hromee or Kbrotech extended assembly when the drain is hard to reach, and choose the Craftsman A19712 only when your model and original part match its compatibility list.
For a plain 1/4 in NPT drain, the Campbell Hausfeld valve is a simple single-part option. The Otoolling and TAISHER packs make more sense when a spare or several replacements are useful.
For tire pressure, the CRAFTSMAN Inflator Gun is the correct type of bleed control. For a regulator knob, the Toobop 137-0001 part addresses that separate repair.
Match the thread, valve style, and included parts before you order. A part that fits the port but does the wrong job will not fix the tank.
Take a moment to picture the repair in daily use. A direct drain cock suits an outlet you can reach without tools, while an extended hose suits a low or blocked outlet.
The easier option is the one you will use after every run.
Check the pressure rating against your compressor as well. A valve rated below your tank pressure is not a safe match, even when the thread is correct.
Keep the compressor manual close by during the comparison.
Care after fitting matters too. Open a new drain slowly at first and listen for leaks around the joint.
A small hiss now is easier to fix than a compressor that keeps running to replace lost air.
Keep the old part until the new one passes that first test. If the thread, handle position, or flow path is wrong, the old valve gives you a clear reference for the next order.
For a wide tank-port repair, the Hromee kit can cover several needs at once, but only if you need those extra pieces. Unused fittings add no value when a single drain cock would do the job.
For model-specific work, slow down and read the compatibility list in full. Model numbers that share the first digits can still use different valves, so an exact match is worth the check.
When reach is the main issue, measure the gap before you choose between the 10 in and 15 in hose options. Extra length helps only when the hose can run in a gentle curve without rubbing or kinking.
If you want a spare for later, a two-pack or five-pack can be sensible, provided the thread and pressure range already match. That plan works best for owners who service more than one unit.
Before using the compressor again, confirm that the replacement is secure, the tank is fully depressurized during installation, and no air leaks appear around the connection. For operating guidance, follow our How To Use Craftsman Air Compressor? guide.

Frequently asked questions
What is the best Craftsman air compressor bleed valve?
The Hromee 5 Piece 1/4 Inch Compressor Air is the strongest general choice because it combines a wing-style drain cock, twist-style petcock, 140 PSI safety valve and hex-head plugs. For a specific Craftsman model, match the compressor model and port before choosing a replacement.
Are Craftsman air compressor bleed valves universal?
No. Many tank drains use 1/4 in NPT threads, but the correct replacement still depends on the drain opening, valve style and available clearance.
Check the old valve, measure the connection and confirm the compressor manual before removing the part.
What is the difference between a bleed valve and a drain valve?
A tank drain valve releases condensed water from the bottom of an air tank. A bleed or relief valve can release air pressure from a line, tire or system.
A safety valve protects against excessive tank pressure, while an unloader valve helps remove pressure from the pump discharge line.
How do you replace a Craftsman compressor tank drain?
Turn off and unplug the compressor, then release all tank pressure before removing the old valve. Match the thread size and seal the replacement as directed.
Open the new drain slowly and check for leaks before returning the compressor to service.
How do you bleed a Craftsman air compressor safely?
Turn the compressor off, disconnect power and let the tank cool. Open the tank drain slowly while keeping your face and hands away from the outlet.
Our guide explains how to bleed an air compressor line when the pressure is in the hose or downstream line.
