ABSTRACT:
Pipe joints are effected by means of a connector unit in the form of a block, that may be moulded of plastics material, having a pair of opposed parallel faces each formed with a blind coupling port separated from an internal passage by a plug or knock-out diaphragm, the passage joining a pair of pipe-receiving ports that are preferably disposed in edge faces of the block. The connector units may be stacked to form a multiple unit with the internal passage of each unit connected to its neighbors through opened coupling ports.
