摘要： A coupler (1) for a low pressure piping system has a hollow metal tube (2) terminating in a pair of end portions (4) defining open ends (10) for slidably receiving and joining together sections of other metal tubes (13) in a substantially air tight relationship. Slots (12) are formed in at least one of the end portions (4) to aid in the crimping of the hollow metal tube (2) by an annular clamp (22). A radial flange (14) is formed adjacent the end portion and receives an annular seal (18) therein. A stop (20) for limiting the insertion of a tube section (13) into the end of the hollow metal tube (2) is formed on the inside of the coupler adjacent the radial flange opposite the slots. The annular clamp (22) encircles the slots (12) and is tightened to clamp the end portions to form metal to metal contact between the metal tubes (13) and to form a seal between the annular seal (18) and both metal tubes (13).
