TR7381 Rigid Metal Valve Extension

Dual-wheel trucks and buses often bury their inner valve stems behind the outer wheel, making routine pressure checks a wrestling match without an extension. The TR7381 solves that with a rigid 77.8mm metal extension that relocates the valve to a position a tech can reach with a standard gauge or chuck.

Its solid metal body threads directly onto the original valve stem, holding its position without the sag or wobble that a longer flexible hose can develop over time. That rigidity keeps the extension pointed exactly where it was installed, service after service.

Because it's built for heavy commercial wheels, the extension is sized to clear dual-wheel spacing on trucks and buses without interfering with the outer tire or rim. It's a straightforward way to speed up inflation checks on fleet vehicles where inner-tire access is otherwise a recurring headache.
