ABSTRACT:
A pipe coupling has a body having a hollow interior including a tubular tail onto which the end of a pipe can be engaged. A coupling nut is captively mounted about the body of the coupling and has a screw threaded interior. When the end of a pipe has been pushed sufficiently onto the tubular tail, rotation of the coupling nut will threadedly engage the nut onto the exterior of the pipe end and draw the pipe further onto the tubular tail of the coupling. The tubular tail of the coupling may be formed as a separate replacable component from the balance of the body of the coupling such that the tail can be removed and substituted by a replacement tail of larger or smaller outside diameter to accomodate larger or smaller pipes.
