Screw-to-Connect Couplings · PS Series

The heavy duty coupling series PS belongs to the category of screw-on type couplings and has been developed especially for the hammer application at construction machines.

It is designed especially for working with high volume flow rates and ensures a low delta p by having an optimum fl ow. For this special application, it has to be ensured that the function and the material of the couplings must be absolutely resistant in case of highest mechanical load.

· High fl ow rates until max. 1000 l/min / 264 US GPM
· Maximum pulse strength
· Zinc/nickel surface for best resistance against corrosion
· Patented valve unit

The patented valve design of the screw-on type coupling ensures that the sealing can’t be rinse out by the volume flow rate. It can handle and resist high and strong impulses, such which appear in the hammer application.


Working Pressure
380 bar / 38 MPa / 5511 PSI

The indicated pressure ratings only apply to the
coupling itself and depend on the connection type.
