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.
Claims10
A pipe connector unit comprised of a block bounded by planar side faces,
- a. said side faces including a first pair of opposed parallel side faces,
- b. each side face of said first pair being formed with a blind coupling port, said block including two knock-out diaphragms normally sealing said coupling ports,
- c. said side faces further including a pair of other side faces each formed with a pipe-receiving port,
- d. said block being formed with an internal passage interconnecting said pipe-receiving ports and bounded by said diaphragms, whereby said coupling ports are in communication with said internal passage when said diaphragms are knocked out.
