Sch 40 PVC bushings are made in three different configurations. Bushings come with spigot by socket, spigot by female pipe thread, and male pipe thread by female pipe thread. These different setups allow the ability to work with many different types of fittings glue or threaded to accomplish your job. Bushings are made to be inserted inside of fittings and cannot be used to reduce pipe. Pipe or pipe nipples are then glued or threaded into the reduced end of the bushing. PVC bushings meet all Sch 40 PVC industry standards and are suitable for potable water service.
