TR4042-G Compact Straight Metal Clamp-In Tubeless Valves

Moving from rubber to metal, the TR4042-G is a clamp-in tubeless valve built around a rigid straight body, sized at 36.5 mm to fit an 11.5 mm valve hole. Unlike a snap-in rubber stem, it is secured to the rim with a nut and grommet, giving it the added rigidity and durability that metal-bodied valves are chosen for.

This shorter, high-performance-grade construction suits wheels where a compact, low-profile valve is preferred, such as wheels with tight brake caliper clearance or a shallow, close-fitting design. The metal body resists the heat and mechanical stress that can eventually fatigue a rubber stem, making it a common upgrade choice for enthusiasts and shops servicing performance vehicles.

Installation takes a bit more time than a snap-in rubber valve since it involves torquing a retaining nut, but the payoff is a valve that holds up better under sustained heat and vibration. The TR4042-G is supplied ten to a pack.
