A failed valve can stop a truck, tractor, pressure washer, or radiator system at the worst possible moment. The difficult part is matching the replacement correctly, especially when similar parts use different numbers, thread types, materials, or mounting angles. These six options cover distinct repair needs, from truck wheels and liquid-filled tractor tires to Simpson pressure-washer pumps and Myson radiator valves. Matching the original part number and application remains the essential first step.

Inside Each Recommended Option
The TR545D designation and 60-degree angle give this aluminum truck stem a clear purpose: replacing a damaged valve on compatible Alcoa 22.5-inch or 24.5-inch wheels. You avoid drilling or altering the wheel because the part follows the original mounting standard.
For a fleet operator, the ten-piece format keeps matching stems together in the workshop. The roughly 90 mm length and 16 mm lower diameter also help you compare the replacement with the removed stem before installation.
Useful Touches
- Aluminum construction gives you a lightweight, corrosion-resistant replacement for compatible truck wheels.
- The TR545D reference supports direct replacement of a compatible 60-degree stem.
- Ten stems give you useful coverage for multi-axle trucks and routine workshop stock.
- Direct fitting avoids the modification work associated with adapting an unrelated valve.
Things To Consider
- You need an Alcoa wheel with a matching TR545D 60-degree valve arrangement.
- The specified dimensions should be checked against the original stem before fitting.
Key Specs
Built With In Mind
You benefit most from this set when maintaining compatible aluminum truck wheels with original TR545D 60-degree valves.
Another Choice May Suit
Camrusic TR618A Valve fits air-and-liquid service on tractors and industrial equipment rather than these truck wheels.
Two valve standards in one set make this a practical choice for maintenance work involving different tractor configurations. The brass construction suits agricultural service, while the air-and-liquid design supports tires that need inflation or liquid ballast.
You gain more flexibility than a single-standard purchase, particularly when your equipment fleet includes both TR218A and TR618A stems. The pack contains ten pieces, which suits repair shops and owners replacing several valves during scheduled servicing.
Useful Strengths
- TR218A and TR618A references cover two common tractor valve configurations.
- Brass material gives you a robust-looking option for demanding tire-service environments.
- The air-and-liquid design fits tractors that use liquid ballast systems.
- Ten valves support fleet maintenance and reduce repeated trips for a single fitting.
Honest Caveats
- You must verify the original valve number because the set includes two standards.
- Manual measurements can vary by roughly 5 mm, so physical fitment deserves a close check.
Quick Facts
Made For
You get the most value from this set when maintaining a mixed fleet of tractors with TR218A or TR618A valves.
A Better Fit Elsewhere
Camrusic TR545D 60 Degree Valve Stems, 10 Pack suits compatible truck wheels rather than tractor liquid-ballast systems.
A thermal relief valve is a pressure-related service component used in certain pressure-washer pump systems, so matching the pump and thread is more important than choosing by appearance alone. This valve carries the 7101359 reference and a 1/4-inch MPT connection, with sealing tape included for the fitting.
You gain a purpose-built service part for compatible Simpson Cleaning pumps and AAA triplex plunger pump applications. Its specified 140-degree rating makes the temperature reference another useful comparison point during equipment diagnosis.
Good Reasons To Consider
- The 7101359 number gives you a direct reference for matching the original component.
- MPT identifies a tapered pipe thread, allowing you to check the pump connection before installation.
- Included Teflon tape helps you prepare the threaded joint during fitting.
Where It May Fall Short
- You need a compatible Simpson or AAA triplex pump, not a general-purpose radiator valve.
- Confirm the 7101359 reference and 1/4-inch MPT connection before disturbing the pump fitting.
The Right Fit
You need this valve when servicing a compatible Simpson Cleaning pressure washer using an AAA triplex pump and the specified 7101359 component.
Look Elsewhere When
Myson TRV2-Way Valve Head belongs on a thermostatic radiator valve and does not replace this pressure-washer pump component.
This TR618A stem is built around the practical needs of tubeless tires that need both air pressure and liquid ballast. Its larger opening supports air or liquid filling, while the clamp-in design allows installation through a standard 5/8-inch valve hole without replacing the surrounding wheel hardware.
For agricultural and industrial work, the brass body, EPDM rubber, and fast-flow core provide several fit and service details to compare. The stated 90 PSI limit and 212-degree core rating give you useful boundaries when assessing the equipment.
A Strong Showing
- The large opening makes air and liquid filling more practical.
- Brass and EPDM rubber combine durable materials for tractor tire service.
- The clamp-in stem fits standard 5/8-inch holes without relocating the wheel hardware.
- The fast-flow core supports routine inflation tasks on tubeless tires.
- Ten stems give repair shops a practical supply for several machines.
Some Limits To Know
- The listed operating limit is 90 PSI, so you should compare it with your tire requirements.
- The valve core carries a 212-degree rating, which may restrict use in unusually hot service locations.

Swap It Out When
Camrusic TR545D 60 Degree Valve Stems, 10 Pack is the closer choice for compatible Alcoa truck wheels.
Repairing a Myson thermostatic radiator valve does not always require replacing the entire assembly. This standard replacement head lets you address a worn head while retaining the existing valve body, which can simplify parts handling and installation.
Your existing valve must be the compatible two-way Myson model. The head also replaces the Contract version, which lacks red markings and uses a black lower section with a white triangle rather than a white section with a black triangle.
Points In Its Favor
- You retain the original two-way valve body instead of replacing the full assembly.
- The interchangeable Contract-head format gives you a useful cross-reference when identifying an existing part.
Small Caveats
- Only the head is supplied, so you need a serviceable Myson valve body already in place.
- The marking differences between Standard and Contract heads deserve attention before fitting.
Who Should Grab It
You need this head when repairing a Myson TRV 2-Way valve whose body remains usable and whose original head matches the standard or Contract format.
Reach For A Different Pick When
Myson TRV2-Way Valve Head offers a stated liquid-filled sensor and broader TRV-head compatibility for a different radiator-valve setup.
The liquid-filled sensor is the defining detail here. A liquid-filled sensor responds to temperature changes within the thermostatic radiator valve, so this replacement head gives you a temperature-sensitive component without replacing the entire valve body.
Compatibility extends across Myson TRV heads according to the stated fit, making this a more flexible choice than the standard-head option. You still need to confirm the two-way valve arrangement and make sure the existing body can accept the replacement.
What It Does Well
- The liquid-filled sensor provides the temperature-responsive element needed by a thermostatic head.
- Stated compatibility with Myson TRV heads gives you broader interchangeability across compatible radiator valves.
- Replacing only the head preserves a serviceable existing valve body.
Points To Keep In Mind
- You receive the head only, not the complete radiator valve assembly.
- Your existing valve body must be compatible with the two-way Myson TRV arrangement.
Core Details
Made For
You need this head for a compatible Myson two-way thermostatic radiator valve whose body remains in serviceable condition.
Another Choice May Suit
Myson Standard TRV 2-Way Head is the more specific choice for a Standard head or an interchangeable Contract head without red markings.
Match the Valve Before Ordering the Part
Start with the system rather than the abbreviation. TRV-related parts include truck tire valve stems, tractor air-and-liquid valves, pressure-washer thermal relief valves, and radiator thermostatic heads. Their shapes and functions differ enough that a similar appearance offers little reassurance.
Confirm the original reference
Read the number stamped on the removed component or locate it in the equipment documentation. TR545D, TR218A, TR618A, and 7101359 identify different applications, while Myson TRV2-Way describes a radiator-valve configuration rather than a tire fitting.
Match the connection and installation
Thread type, wheel-hole diameter, stem angle, and mounting method determine whether a part will fit. You should also check pressure and temperature limits against the equipment rather than treating a valve as a universal replacement.
Decide Between a Full Valve and a Head
A complete valve is necessary when the body is damaged or absent. A replacement head works only with a compatible, serviceable body, so inspect the existing assembly before ordering the smaller component.
Common Mistakes in Valve Replacement
Mistakes Worth Dodging
Avoid ordering from the application name alone. Match the original part number, dimensions, and connection details, and do not assume a tire valve, pressure-washer relief valve, and radiator head are interchangeable.
What Separates Premium From Basic
A higher-cost choice may add a defined material, temperature rating, sensor, or multi-standard fitment. Paying more makes sense only when those details match the repair and eliminate the need for modification or repeated parts purchases.
Frequently Asked Questions
What Does TRV Mean in a Valve?
TRV can refer to several valve-related parts, including truck tire stems, tractor liquid valves, pressure-washer thermal relief valves, and thermostatic radiator heads. The manufacturer, part number, and equipment application identify the correct category.
How Do I Find the Correct Replacement Valve?
Compare the original part number with the listing first. You should then confirm the thread, wheel-hole size, stem angle, pressure rating, temperature rating, and mounting method.
Are TR618A and TR218A Valve Stems Interchangeable?
You should not treat them as interchangeable because they represent different valve standards. Verify the number on the original component and match the required application before purchasing.
Can I Replace Only a Myson Radiator Valve Head?
You can replace only the head when your existing two-way Myson valve body is compatible and remains serviceable. Confirm the head markings and the valve-body configuration before fitting the component.
Is the 7101359 Valve a Radiator Head?
No, the Zewool 7101359 is a thermal relief valve for compatible Simpson Cleaning pressure-washer pumps using AAA triplex pump applications. Its 1/4-inch MPT connection distinguishes it from the Myson radiator components in this list.
Final Verdict
Your safest choice starts with the original part number, followed by a close check of the connection and installation method. Use the TR545D and TR618A options for their specified tire applications, the 7101359 valve for compatible Simpson pump service, and the Myson heads when the existing radiator-valve body remains usable.
