Valve , unassembled, passenger car, light truck

The HOFMANN POWER WEIGHT concealed valve is lighter than brass valves. The special design protects against sabotage and prevents the valve from breaking off in the field.

Rim valves for tubeless car and van tyres. Ø 11.3 mm Description: Hidden valve packing unit: 1 set tightening torque: 7-10 Nm

When should metal valves be replaced? The best thing to do is to change the tyres every time!

The tyre valves are subjected to enormous stress during their service life and are exposed to many different environmental influences. These include varying levels of ozone, solar radiation and the use of chemicals. It does not matter whether it is a rim valve for cars, trucks or bicycles or what material (rubber or metal) it is.

For this reason, every time a tyre is changed in the workshop, not only the tyres and rims but also the valves should be inspected and tested. A safe driving experience can only be guaranteed with a regular check of the metal valves. Potential tyre pressure loss can be caused by defective rubber valves or metal valves. In addition, external damage to the car tyre or corrosion of the valve core can also be the cause.

The consequences of tyre pressure loss include various safety risks, with increased tyre wear, increased rolling resistance and increased fuel consumption among the less dangerous ones. However, broken rim valves can have the negative effect of increasing braking distances and can lead to unsafe driving behaviour with the risk of losing control of the vehicle.
