TR4 Tire Valve Stem Rubber Base Metal Valve Stem for Inner Tube Tires
TR4 Tire Valve Stem is a metal valve stem designed for inner tube tire applications. It features a rubber base combined with a threaded brass stem structure, providing reliable air retention and secure installation for motorcycle, industrial, and specialty tire tubes.
Unlike tubeless snap-in valve stems such as TR413 or TR414, the TR4 valve stem is designed to be vulcanized or mounted into an inner tube, making it suitable for tube-type tires where a durable and stable valve connection is required.
TR4 Inner Tube Valve Stem is widely used in motorcycle tires, agricultural equipment, industrial vehicles, and other tube tire applications requiring a compact metal valve solution.
Metal MaterialRust and corrosion resistance, durable and long-lasting.
Clamp in installationHigh speed driving with bumps and no detachment, better air tightness.
Special for vacuum tiresStandard specifications, compatible with the vast majority of motorcycle wheels.
