Mercedes SL R129 hydraulic line port seal kit - cylinders

We offer a complete hydraulic line port seal repair kit for all 12 hydraulic cylinders used in Mercedes SL R129 models. 


These seals are located within the hydraulic ports of the cylinders and consist of a uniquely shaped quad seal and a CNC machined brass support ring to keep the seal in place. Two quad seals and two brass support rings are needed per cylinder. The support rings are CNC-milled to our specification in Germany within tolerance class DIN ISO 2768-1-f (fine) and then precision ground to ensure a high level of accuracy.



Attention: Special tools are needed for the removal of the old and insertion of the new brass support rings.

Attention: The provided seals may only be used with the following types of hydraulic fluid to ensure smooth operation and a long service life:
- Genuine Mercedes Benz hydraulic fluid MB 343.0, hydraulic fluids in accordance with standard DIN 51 524, HLP 32 or standard ISO 11158, HM 32
