A dust cap is essential to protect the TPMS valve stem of a vehicle to prevent dust or other small particles from entering the valve and damaging it.
The dust cap also forms a pressure seal, helping to prevent deflation of the tyre due to slight air seepage past the tyre valve. The dust cap is internally threaded and is secured by screwing it onto the end of the stem.
You should never use metal dust caps on any valve stems as they can corrode and bing or corrode onto the stem. Therefore It is important to use plastic dust caps on TPMS valves.
These caps have rubber seals inserted to stop water ingress and provide a second seal for the valve, this ensures accurate tyre pressure reading.
