Power Steering Line/Hose: Description and Operation

The principle of the plug-in couplings for the pressure and return lines is the same. It is the diameter of the plug-in coupling and of the pipelines that differ (return line = large diameter/pressure line = small diameter).

Plug-in couplings are components that permit simple, fast and precise connection of pipelines. These precision components must be handled carefully during repairs. Excess force during assembly work, damage to the sealing surface and soiling can cause leakage.
