R13R Standard Brass-Core Passenger Tube Valves

The R13R is a standard inner tube valve for passenger cars, built to the long-established TR13 pattern. It measures 35.0 mm and is sized for an 11.3 mm valve hole, arriving complete with a brass valve core and cap already installed and ready to mount.

As one of the most widely used tube valve patterns on passenger vehicles, the R13R fits the inner tubes commonly found on smaller wheel diameters and older or entry-level vehicle platforms still running tube-type tires. Its brass core resists corrosion better than lower-grade alternatives, helping maintain a consistent seal over the life of the tube.

Because it comes with the core and cap pre-fitted, the R13R saves an assembly step during tube replacement or repair, which is useful for shops handling high volumes of routine tube service. Supplied in packs of ten.
