Snap-In Valve Details

The TR418 is a rubber snap-in valve stem with a metal jacket - designed for alloy and forged wheels where direct rubber-to-metal contact can cause galvanic corrosion or rim galling. The reinforced metal sleeve protects the valve hole seat while providing a secure, airtight seal. Fits 0.453" valve holes.

Metal Jacket: Reinforced metal sleeve prevents direct rubber-to-rim contact, protecting alloy and forged wheel surfaces from corrosion and galling.
Valve Hole: 0.453" - fits the standard diameter on most passenger car, light truck, and alloy wheel applications.
Max Cold Pressure: 65 PSI - rated for all standard passenger and light truck tire inflation pressures.
EPDM Rubber Body: Weather and ozone-resistant compound provides a reliable, long-lasting airtight seal.
Standard Schrader Core: Chrome-plated core for consistent, leak-free inflation and deflation.
Pack Size: Sold in 100-piece bags - standard shop quantity for tire service operations.

Frequently Asked Questions (FAQs)

What is the metal jacket on the TR418 and why does it matter?

The TR418 has a reinforced metal sleeve around the rubber body that prevents direct rubber-to-metal contact at the valve hole seat. On alloy and forged wheels, that contact can cause galvanic corrosion over time, degrading the seat and making future stem removal difficult. The metal jacket protects the rim and allows for clean removal at the next tire change.

When should I use a TR418 instead of a TR413?

Use the TR418 on alloy, forged, or billet wheels where rim protection matters, or when the 2-inch overall length is needed for a deep-drop wheel profile. The TR413 is the call for standard applications where length and cost are the main factors.

What is the TR418 made of?

EPDM synthetic rubber body with a reinforced metal jacket, conforming to SAE J1205/J1206 standards. The chrome-plated brass Schrader core comes pre-installed. The metal jacket adds rim protection without compromising the EPDM seal.

Can the TR418 be used on TPMS-equipped wheels?

No. TPMS sensors require a dedicated TPMS valve stem. The TR418 is for non-TPMS tubeless wheels only.

How often should valve stems be replaced?

OEM guidelines recommend replacing rubber valve stems every time new tires are mounted. Rubber degrades from ozone exposure, heat cycling, and age, which can cause slow leaks even when the tire itself is fine.
