Replacing Rubber Snap-in TPMS valves

Over the past couple of years many manufacturing brands have started to move away from the metal clamp-in valve stems and switching to there rubber snap-in counterparts instead. The reason for this is that metal valve stems are more susceptible to corrosion than the rubber options, major contributions to this change are certain climates, salt, sand, humidity and traffic film.

Valve stems which are corroded are a problem and cause bigger issues like air leaks and broken parts can occur during the dismount procedure.

It is recommended to change the service kit on all metal valves at every tyre change. This will stop the rubber grommet from perishing or even fusing itself.

Its rubber snap-in counterpart however offers a corrosion-resistant solution. not only are the rubber variations of the valves more resistant to corrosion they are easier to install and have less components.

However, although the snap-in valves are more resistant to corrosion, they are not completely damage proof and is still best practice to change at every tyre change. The rubber on the valve stem can begin to dry out causing cracks and tears.

The best way to protect yourself and customers from potentially costly repairs it is best to make changing a service kit or a valve the best practice. Regardless if you are changing a rubber snap-in or a metal clamp-in there is usually enough wear and tear to justify a new valve or service kit.

In general service kits are not an expensive outlay, the cost should automatically be included and considered a vital step in looking after tpms valves.
