Walther Series EH Hook-in couplings are a thru type (non-valve) coupling system designed for use in various industries including chemical, food processing and pharmaceutical. Used for the movement of viscous, pasty, powder and pellet media, a maximum static working pressure up to 725 psi can be achieved depending on the bore size. Connecting the coupling components requires zero clearance and is performed by placing the adaptor, with a face seal, into the coupling nut slit and tightening the coupling nut using either the ribbed sleeve or by the "c" spanner bores. Any leakage due to wear of the face seal can be eliminated by further tightening of the coupling nut.
