ABSTRACT:
A coupler for interconnecting in fluid communication a pair of axially aligned flexible pipe ends, employs a tubular member for insertion between two sections of drainpipe to be coupled. A first thread is included on a first end portion of the tubular member for threaded engagement of a first one of the two sections of drainpipe, along with a second thread on a second end portion for threaded engagement of the second section. An integrally formed annular flanges in one form of the invention serves as a grip with which to manually screw the tubular member onto the drainpipe, while a cutback portion on the flange prevents misalignment of the coupled sections at the coupling when placed upon the ground. Tapered end pieces that screw onto each end to accommodate smaller drainpipe are provided in another form, with the threads of the tubular member matching the helically-corrugated plastic casing surface of conventional RV drainpipe.
