TR7793R Standard Rubber-Base Truck Tube Valves

Cross-referenced historically as the TR78A, the TR7793R is the mid-length option in the rubber-base truck and bus tube valve family, measuring 129 mm. Like the shorter TR7823R, it uses a vulcanized rubber base bonded directly to the tube for a durable, permanent seal.

At nearly double the length of the TR7823R, the TR7793R suits truck and bus rim configurations where the valve needs to reach further from the tube's mounting point to clear the rim structure or dual-wheel spacing. The vulcanized bond holds up under the sustained high pressures and heavy-duty cycling typical of commercial tube use.

Tube manufacturers and heavy-vehicle repair specialists commonly stock the TR7793R as the standard mid-range length in this family, using the shorter TR7823R and longer TR1396R for the shallower and deeper fitments respectively. Packed ten per box.
