ABSTRACT:
This invention relates to a plastic pipe fitting having a connecting portion for attachment to another fitting and a joining portion to be fuse bonded to a length of pipe, whereby successive lengths of plastic pipe may be releasably connected. The connecting portion consists only of plastic suitably reinforced to increase its mechanical strength, primarily the flexural modules above the flexural modulus of the joining portion of the fitting and compatible with the flexural modulus of a mechanical couplings to provide a reliably effective connection between adjoining pipe lengths. The connecting portion of the pipe lengths desirably shaped to conform with the configuration of a conventional coupling commonly used to connect metallic pipe lengths.
