TR414 EPDM Rubber Tubeless Snap-In Valves | Hole Size: 0.453" | Height: 1.50" | MCIP: 65 PSI | MRT: 0.156"

The TR414 is an industry-standard rubber snap-in tubeless valve stem used in professional tire service for passenger cars and light trucks. It is defined by a 0.453-inch (11.5mm) rim hole diameter and a 1.50-inch installed height, and is rated to 65 PSI maximum cold inflation pressure; verify application against the tire/wheel assembly requirements.

For tire shops, replacing rubber snap-in valve stems is a small step that helps prevent avoidable comebacks and warranty claims. Old rubber valve stems can crack, fatigue, or leak over time, especially after exposure to heat, cold, ozone, road chemicals, and repeated tire service. 

Best practice for shops: Replace valve stems when installing new tires, and inspect them any time you demount a tire. A fatigued or cracked TR414 rubber valve stem is one of the leading causes of slow leaks after tire service.

Why shops prefer a TR414 rubber valve stem:

•    OEM-grade EPDM rubber: resists ozone degradation and UV exposure across all climates, matching or exceeding OE stem longevity

•    High-temperature brass valve core: rated for sustained heat cycles; helps resist heat and corrosion in demanding shop environments

•    100% factory ozone and leak tested: every snap-in valve stem individually verified before packaging

•    OEM standard 0.453" (11.5mm) diameter: installs in any standard tubeless rim hole, passenger car or light truck, no modification required

•    65 PSI MCIP rated: meets RMA/TIA TR4 standard for passenger and light truck tubeless tire valves

•    Available in bulk: Box of 50 for shop use, Box of 500 for high-volume operations

TR414 vs. TR418: The TR414 (1.50" height) is the standard choice for most passenger car and light truck wheels. Choose the TR418 (2.00" height) for deep-well rims or custom wheels where access is restricted.

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

Common FAQs

What is a TR414 valve stem?
A TR414 is a rubber snap-in tubeless tire valve stem designed for standard 0.453" rim holes. It has a 1.50" installed height and is commonly used in passenger car, SUV, and applicable light truck tire service.

What is the difference between TR414 and TR418?
The TR414 has a 1.50" height, while the TR418 has a 2.00" height. Choose TR418 when the wheel design requires more valve stem access.

What PSI is a TR414 valve stem rated for?
TR414 snap-in valve stems are commonly rated for a maximum cold inflation pressure of 65 PSI. For assemblies requiring more than 65 PSI, use the correct high-pressure valve.
