TR7823R Short Rubber-Base Truck Tube Valves

The TR7823R is a short truck and bus inner tube valve, historically referenced as the TR75A, built with a rubber base and vulcanized directly to the tube for a permanent, leak-resistant bond. At 74 mm, it is the shortest of the three lengths in this rubber-base family.

The vulcanized rubber base creates a stronger, more durable seal than a valve simply pressed or threaded into place, which matters on truck and bus tubes that see high inflation pressures and heavy repeated loading. Its shorter length suits wheel and rim combinations where the valve hole sits closer to the tube's mounting surface.

Because vulcanized valves are typically installed at the tube manufacturing or major-repair stage rather than swapped in the field, the TR7823R is most often used by tube manufacturers and specialist repair shops working on commercial truck and bus tires. Supplied ten to a pack.
