TPMS Sensor Valve Caps for your vehicle. Unlike older vehicles tyre pressure monitoring system dust caps are grey to easily identify the car is equipped with TMPS sensors. When changing your tyres you will rarely get given new caps and often the get lost. A dust cap is essential to protect the TPMS valve stem to prevent dust or other small particles from entering the valve and damaging it.
These grey Valve caps 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 bind 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.
