This Spears 437-211 schedule 40 white PVC bushing has a 1-1/2" spigot on one end and 1" socket on the other end for connecting two unthreaded pipes of different diameters. It is made of white PVC (polyvinyl chloride) for chemical and corrosion resistance, strength, and less weight than a metal fitting. This bushing can be connected to other materials such as steel, copper, or cast iron using metal-to-plastic transition fittings (sold separately) and is suitable for cold-water pressure distribution systems including irrigation, pool and spa, potable water, and chilled water. This PVC fitting has a maximum operating temperature of 140 degrees F, meets ASTM International D1784 and D2466 standards for quality assurance, and is certified by NSF International for potable water service.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).
