More Information
Summary:A pipe fitting (10) for plain end pipe is formed of housing portions (12, 14) defining receptacles(16, 18) for receiving pipe elements. The receptacles are coaxial with respective axes oriented angularly with respect to each other. Each receptacle has a channel (26, 28) that faces a respective axis with floors at different radii of curvature. Retainers (42) are received within the channels. The retainers have teeth and one or more offset tabs that cooperate with the channels to prevent improper assembly of the fitting. Ring seals are received within channels positioned adjacent to the receptacles. The ring seals cooperate with the retainers to hold the segments in spaced relation sufficient to insert pipe elements into the receptacles when the fitting is pre-assembled. Apertures (8) are provided in the receptacles to permit visual determination of the presence of the retainers post assembly.
