If the gas spring is used in a particularly dirty or dusty environment, it may be necessary to protect the seal by using protective caps made of rubber or plastic. The protective cap is intended to ensure that no dirt and dust particles in the environment penetrate into the pneumatic spring seal when actuating the flap. Using the protective cap therefore also has a positive effect on the service life of the gas spring in these installation situations.
In an extremely dirty environment, the protection that is guaranteed by the protective cap may not be sufficient. In these extreme environmental conditions, it is advisable to use a Space-Mat gas spring (gas spring with lubrication reservoir) from SUSPA.
