Tubeless Tire Valve
A valve specifically designed for tubeless tires, which allows air to be inflated into the tire and retained, without the need for an inner tube. It provides a hermetic seal against the rim.
Types of Tubeless Tire Valve
Rubber Snap-in Valves: Most common for passenger cars and light trucks. A rubber body with a metal core snaps into the rim hole.
Metal Clamp-in Valves: More durable, often used for higher performance vehicles, trucks, buses, and motorcycles. The metal body is secured to the rim with a nut.
High-Pressure Valves: Designed for higher tire pressures.
TPMS (Tire Pressure Monitoring System) Valves: Integrate a TPMS sensor into the valve stem.
Applications in Various Industries
Automotive: Passenger cars, light trucks, SUVs.
Commercial Vehicles: Trucks, buses.
Motorcycles & Scooters: Tubeless tire applications.
Bicycles: Increasingly common on mountain bikes and road bikes.
Industrial/Agricultural Equipment: Some tubeless applications.
Material Selection Considerations
Valve Stem/Body:
Rubber: EPDM (Ethylene Propylene Diene Monomer) or natural rubber for good elasticity, ozone resistance, and temperature range.
Metal: Brass (nickel-plated) for durability and corrosion resistance (for clamp-in and valve cores). Aluminum for lightweight options.
Valve Core: Brass, often nickel-plated, with stainless steel spring and rubber seals (NBR).
Grommet/Seal (for snap-in): EPDM or natural rubber.
Cap: Plastic (ABS, PP) or metal (brass, aluminum).
Nut (for clamp-in): Brass or aluminum.
TPMS Sensor Housing: Durable plastic (e.g., PA66 GF) or metal.
