Abstract
A coupling for joining pipe segments together is disclosed. The coupling is derived from a standard fitting and has a housing with a socket and a first expanded region adjacent to the socket and a second expanded region adjacent to the first expanded region. A sealing member is positioned in the first expanded region, a retainer is positioned in the second expanded region and a support washer having transversely oriented radial and coaxial flanges is positioned adjacent to the retainer. A clamping tab turned inwardly on the second expanded region overlaps the radial flange and clamps the support washer and retainer against a shoulder within the second expanded region thereby also capturing the sealing member within the coupling. The retainer has a plurality of radial teeth angularly oriented to engage a pipe and prevent its removal from the coupling. The teeth are twisted about their longitudinal axes.
