ABSTRACT:
A pipe fitting for interconnecting two sections of pipe and comprising an interior male portion having a band of flexible material bonded to the outer surface, a female portion, and end of which is positioned over and slidably engaged over the elasomeric ring, to allow rotative movement of the female portion with respect to the male portion, so that an angle of deflection may be achieved between the first section of pipe and the second section of pipe engaged into the fitting. There is further provided means on the interior of the fitting for allowing unrestricted flow of fluid at least in a single direction through the fitting as the fitting is deviated through the range of angles in its use.
