Multiple pressure oil hose coupling - has metal block with sealing rings retained in nipple receiving bores by support rings and end plate

摘要

The coupling is particularly intended for connecting a number of flexible hydraulic high-pressure lines. It comprises a sealing block (21) which is releasably retained in the housing of one coupling half and has a number of bores (24) with seals (63) for receiving the nipples at the ends of the flexible hoses, as in 2845926. The block is made of metal, and at least one end of each bore is stepped (61) and has a nipple sealing ring (63) located on the shoulder via a support ring (64). The support rings are retained by a plate (65) which is secured on the end face (22) of the block and has bores (66) aligned with, and of the same diameter as, the coupling bores.
