What Are Tire Valve Caps?
Tire valve caps are small screw-on covers made to fit within the valve stem of one's vehicle’s tires. The valve stem will be the part that allows air to penetrate and exit the tire.

They prevent dust, sand, and small debris from entering the valve stem, that could lead to air leaks or valve malfunction.
Moisture Barrier
Valve caps assist in keeping water out of the valve system. Moisture can freeze in cold temperatures, potentially inducing the valve to crack or leak.
Air Pressure Maintenance
Although the valve core is designed to hold pressure, a cap offers an extra seal to prevent slow leaks, making an effort to maintain optimal tire pressure.
Prevent Damage to Valve Core
Caps can prevent physical damage to the valve stem and its internal components, especially in rough driving conditions.
