EDPM Rubber Tubeless Snap-In Valves | Hole Size: 0.453" | Height: 2.00" | MCIP: 65 PSI | MRT: 0.156"

The TR418 rubber snap-in tubeless valve stem is a 2.00" valve stem for professional tire service applications where extra height is needed for easier inflation access. It fits standard 0.453" / 11.5mm rim holes and is rated for 65 PSI maximum cold inflation pressure.

When to Use a TR418

Choose the TR418 when the wheel design requires more valve stem clearance than a standard TR414 provides:

• Deep-well rims: the 2.00" height provides added reach where a shorter stem is difficult to access
• Custom and aftermarket wheels: for wheel designs where the valve sits deeper in the rim
• Restricted inflation access: makes inflation, pressure checks, and service easier at the bay
• Specified TR418 applications: use when the wheel, vehicle, or service information calls for a TR418

TR418 vs. TR414

The TR418 and TR414 both fit standard 0.453" / 11.5mm rim holes and are rated for 65 PSI maximum cold inflation pressure. The difference is height:

TR414: 1.50" installed height
TR418: 2.00" installed height

Choose the TR414 for standard passenger car and light truck applications. Choose the TR418 when the wheel design requires a taller stem for easier access.

Important Application Note

Do not use a 65 PSI snap-in valve stem on assemblies requiring inflation above 65 PSI. Certain LT, ST, commercial, trailer, or performance applications may require a high-pressure snap-in or metal clamp-in valve. Always verify the correct valve type for the wheel, tire, and inflation requirement before installation.

FAQs

What is a TR418 valve stem?
A TR418 is a rubber snap-in tubeless valve stem with a 2.00" installed height. It fits a standard 0.453" / 11.5mm rim hole and is used when extra valve stem height is needed for easier inflation access.

What is the difference between a TR418 and TR414?
The difference is height. The TR418 is 2.00" tall, while the TR414 is 1.50" tall. Both fit 0.453" / 11.5mm rim holes and are rated for 65 PSI maximum cold inflation pressure.

When do I need a TR418 instead of a TR414?
Use a TR418 when the wheel design requires more clearance than a TR414 provides, such as deep-well rims, custom or aftermarket wheels, or any application where a shorter stem is hard to reach with an inflation chuck.

What PSI is a TR418 rated for?
The TR418 is rated for 65 PSI maximum cold inflation pressure. For assemblies requiring more than 65 PSI, use the correct high-pressure snap-in or clamp-in valve.
