These seals are located within the hydraulic ports of the valve block and consist of a uniquely shaped quad seal and a CNC machined brass support ring to keep the seal in place. 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.

- 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
