Insertion tool for the Mercedes hydraulic line port seals

We offer an insertion tool for the hydraulic line port seals used in various Mercedes models. 


These seals are located inside the hydraulic line ports of the cylinders, the distributors, the valve blocks and the hydraulic pump (depending on the model) and consist of a uniquely shaped quad seal and a brass support ring to keep the seal in place. With this special insertion tool you can install the quad seal and the brass support ring at the correct insertion depth.

The insertion tool is made out of heat-treated 1.4034 / X46Cr13 / AISI 420C stainless tool steel that offers high hardness and very good wear and corrosion resistence. It is CNC-milled to our specifications within tolerance class DIN ISO 2768-1-f (fine) in Germany to ensure a high level of accuracy.


Attention: This insertion tool is only supposed to be used for the installation of our hydraulic line port seals. The old hydraulic port seal must be removed with a special extraction tool (product number MJ10522) before the new seals can be installed.
