Abstract
A pipe coupler assembly comprises a fitting which is securable to the ends of a pair of pipes. The fitting comprises a socket portion for receiving the pipe end. A plurality of tabs project rearwardly and outwardly from the socket portion and are disposed in circumferentially spaced relationship about a longitudinal axis of the fitting. The fitting also includes a circumferentially extending, radially outwardly open channel disposed forwardly of the socket portion. The channel extends radially inwardly relative to the socket portion and is adapted to receive a resilient seal ring. A generally radially extending shoulder is disposed between the tabs and the channel. This shoulder is adapted to engage an edge of the pipe end to limit insertion of the fitting. The assembly also includes a generally cylindrical, open-ended sleeve. The sleeve is sized to receive the fittings through axially aligned chambers thereof. The fittings are insertable into the chambers, with the tabs being initially inwardly flexed and then springing into securing engagement with recesses in the chambers, and with a seal ring in the channel being compressed sealingly against the chamber walls.
