TRIPLE-EXPANDED MECHANICAL PIPE COUPLING DERIVED FROM A STANDARD FITTING
Document Type and Number:
WIPO Patent Application WO/2004/046596
Kind Code:
A2
Abstract:
A coupling (10) for joining pipe segments together is disclosed. The coupling is derived from a standard fitting and has a housing with a socket (12) and a first expanded region (20) adjacent to the socket, a second expanded region (26) adjacent to the first expanded region and a third expanded region (29) adjacent to the second. A sealing member (42) is positioned in the first expanded region, a retainer (44) is positioned in the second expanded region and a support washer (45) having transversely oriented radial and coaxial flanges is positioned adjacent to the retainer in the third expanded region. A lip (32) turned inwardly on the second expanded region overlaps the radial flange and captures the support washer, retainer and sealing member within the coupling. The retainer has a plurality of radial teeth (60) angularly oriented to engage a pipe and prevent its removal from the coupling.
