Seal kit hydraulic cylinders (soft top system)

Seal kit hydraulic cylinder (Soft top system)

Many owners of Mercedes SL cabriolets know the problem: After some time the hydraulic cylinders, which handle the opening and closing of the soft top, leak and therefore do not work properly anymore.

This happens because of the cheap materials used by Mercedes for the o-ring and the rod ring. These materials cannot handle high temperatures (which are even increased by the pressure within the hydraulic cylinder) and leak after some time.

For this reason, we offer rod rings made of the standard material AU (red color) as well as rod rings made of a Viton compound (brown color). While Viton has the same positive hydraulic properties as AU, it also can resist temperatures up to 200°C and is more durable.

Whether you should use the rod rings made of AU (red color) or the rod rings made of Viton (brown color), depends on how long the rod rings should seal the hydraulic cylinder. Usually Viton is more durable and heat resistant, therefore the rod rings made out of this material have a longer lifetime. Of course this material is a bit more expensive than AU.

The rod ring and the o-ring are, like all products we offer, made by a german brand manufacturer and guarantee a long lifetime without losing their functionality.
