Valves

ARE YOU USING THE RIGHT VALVE?
There are two main types of valves for passenger cars and vans.

 

 

”Snap-In”         ”Clamp-In”
Rubber valve  Metal valve

The valves are designed for different maximum pressures!

Rubber valves are available in two versions: the standard rubber valve, which can cope with a pressure of max 450 kPa, and the high-pressure rubber valve, which can cope with max 700 kPa.
The metal valve can take a pressure of max. 1400 kPa.

WATCH OUT!
If the vehicle has a recommended tyre pressure close to 450 kPa or more, there is a risk that the vehicle owner will fill them to a higher pressure. Tyre pressure also goes up when the tyre gets hot.
In these cases, a standard rubber valve should not be used, but instead a high-pressure valve or metal valve should be chosen.
This problem is not uncommon on mobile homes and caravans!
We strongly recommend using a metal valve at speeds over 210 km/h. There is a high risk of rubber valves bending at high speeds, with ensuing air leakage.
