4PCS TR416 Valve Stem, Copper Rust-proof Waterproof Car Tire Sealing Tool, Outer Mount High-pressure Tire Valve, Universal for Most Cars, Trucks, SUVs (Silver)

1. The valve stem maintains tire pressure, ensuring a tight connection between the valve stem and tire during vehicle movement and over bumpy conditions, eliminating the risk of air leakage2. The core components of the valve stem are made of high-quality copper, which is rust-resistant, has high metal hardness, and strong impact and deformation resistance, resulting in a service life far exceeding that of ordinary plastic valve stems

• Material: The core components of the valve stem are made of high-quality copper, which is resistant to rust even after prolonged exposure to rain and mud. Its high metal hardness provides strong impact and deformation resistance, resulting in a lifespan far exceeding that of ordinary plastic valve stems.
• Main Function: The valve stem is used to maintain tire pressure. Tire valve stems should be inspected regularly for cracks, leaks, or aging, and replaced as needed. This valve stem ensures that no air leaks occur during vehicle operation.
• Reliable Sealing: The valve stem fits tightly against the tire valve bore and valve core, maintaining stable tire pressure even under high pressure conditions and preventing tire leaks or moisture seepage into the valve core.
• External Mounting: The valve stem adopts an external mounting structure, which is convenient and stable to install. It can be adapted to high-pressure tire usage scenarios, ensuring a tight connection between the valve stem and the tire during vehicle driving and bumpy conditions, with no risk of air leakage.
• Precise Dimensions: The valve stem has a top diameter of 0.35 ", a total height of 1.75 ", and a bottom diameter of 0.75 ", strictly adhering to industry standard specifications. It precisely matches the valve bores of most passenger car, truck, and SUV tires.
