Properties:

A fitting having rounded ends where it joins two sections of pipe in a straight line to direct the flow from these ends acting as inlet(s) to the end at right angles. It has an internal shoulder(s) at the end(s) of its internally threaded or unthreaded portion, whose inside diameter conforms to standard weight wrought iron pipe or copper drainage, waste and vent (dwv) tube. When connected, the mating pipe and/or pipe fitting is close to the shoulder to eliminate a pocket and provide a smooth flow of the pipe and/or pipe fitting contents. It may have side and/or heel inlet(s). It is designed to connect two sections of pipe in a straight line to a third section at right angles.
