Coupling for hydraulic connections for palettes for processing machinery has sealing vulcanized into expanded groove in one connection part

摘要

The hydraulic connections have a sealing ring to seal the joint. One connection part (1) has a groove with an inward directed conical expanded section. A sealing ring (3) of corresponding shape is vulcanized into the groove. The slide and sealing surface of the sealing ring forms a plane with the ring face of the connection part. A bead formed during vulcanizing is ground off.
