Mercedes seal kit soft top o-ring o-rings rod seals SL R129 A1298001672
Artikelbeschreibung
Here you have the chance to purchase one seal kit for the hydraulic cylinder in the soft top used in Mercedes models W129/R129.
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 PTFE/Viton compound (brown color). While PTFE/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 PTFE/Viton (brown color), depends on how long the rod rings should seal the hydraulic cylinder. Usually PTFE/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.
Important information: In every hydraulic cylinder there is a rod seal and an o-ring as well as a piston seal, which often times consists of two pieces. This seal kit contains a rod ring and an o-ring and is meant for sealing the hydraulic cylinder if it is leaking. If the piston seal should also be worn out (this does not happen very often), you can find the matching repair kit in our shop.
Attention: Although our rod rings are very durable, they should only be used with the following hydraulic liquids to provide a long lifetime.
- hydraulic fluids in accordance with standard ISO 11158, HM 32 (most hydraulic fluids comply with this standard)
