Inner Tube Valves

Inner tube valves are the air-filling and sealing components fitted directly to rubber inner tubes used in tube-type tire assemblies, still widely specified across passenger vehicles, light trucks, buses, and heavy commercial fleets in markets where tube-type wheels remain standard. Valve integrity is central to tube performance, and consistent manufacturing quality reduces warranty risk for tube producers and tire distributors.

The range covers brass-core valves for passenger car and light-truck tubes, offered in standard and wide-bore sizes, as well as rubber-base valve designs engineered for the higher pressures and heavier-duty demands of truck and bus applications.

All valves are manufactured with corrosion-resistant plating and vulcanization-grade rubber bases to ensure a secure, long-term bond to the tube body, meeting the pressure-holding and pull-out-strength benchmarks expected by tube manufacturers and fleet maintenance operations.

This category is available for private-label supply to inner tube producers, as well as direct distribution to tire service networks, with options for custom branding, bore sizing, and packaging to match regional market requirements.
