Plug-In Couplings For Pipelines (New System)

Plug-in couplings for pipelines

Different plug-in couplings are used for various applications (see Allocation).




Allocation of the plug-in couplings / pipelines


Opening and joining plug-in couplings

Important notes
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.

Perform preparations carefully when handling plug-in couplings - e.g. cleaning and fitting the plugs - as repairs are possible only by replacing the affected line in most cases.

After separating the plug and socket piece, carefully protect them against dirt and scratches with caps.

Join the plug-in connection only in a straight line. Never use excessive force.
Pull slightly to make sure the connection is locked properly.


Steering pressure line and return line





The plug-in couplings are opened by unscrewing.

They are joined by plugging together.

A detailed description about opening and joining is given in Plug In Couplings.


Steering return line on hydraulic pump





To release the return line, press the red unlocking ring (arrows) and simultaneously pull the line out of the hydraulic pump.

Join by plugging together in a straight line. Then pull slightly to ensure that the connection is properly locked.
