The TR801HP is a premium, high-pressure rubber snap-in valve stem engineered specifically for tubeless wheels with a large 0.625" (15.875 mm) rim hole. Designed as a rugged upgrade to standard passenger car valves, it features an enhanced EPDM rubber body and a robust internal brass core. This construction allows it to safely manage the elevated inflation pressures required by heavy-duty commercial and utility applications without the need for a rigid metal bolt-in setup.
