Why do we need to Service Sensors?

When a tyre is replaced or a puncture repaired on a vehicle without TPMS, it is normal practice to replace the rubber valve. With a TPMS sensor it is also important to replace the rubber sealing grommet which deteriorates just like the rubber valve. At the same time as replacing the rubber grommet, it is good practice to replace other parts too.

The Metal Sealing Washer (if fitted) often becomes distorted, replacing this ensures a good seal when re-assembling the sensor.

The Outer Collar is replaced because it becomes metal fatigued, and sometimes badly corroded. This metal fatigue can often make the outer securing collar crack and sometimes this will fall off completely.

The Core is replaced to create a good airtight seal in the sensor internally. Only Nickel plated cores should be used in Metal Valves.

The Cap is replaced with a new pressure cap. Again the rubber washer in the old cap deteriorates, replacing the cap helps keep the sensor airtight and free from debris, or fluids that might affect the operation of the core.

We are supplying these complete valves so they are handy to have in your glove box ready for every time you have a tyre changed. Just hand a valve to the tyre bay mechanic and they’ll fit them for you with every tyre change. This also saves you money on not having to buy a new sensor when your current one works fine, use these replacement valves to maintain the sensors.
