The Parker reducing bushing is a stainless steel 316 pipe fitting with male National Pipe Taper (NPT) threads on one end and female NPT threads on the other for connecting two different types of pipe. It has male NPT threading on the outside and female NPT threads on the inside for creating tighter seals than straight threads. The reducing bushing is made from stainless steel 316, which is higher strength and more corrosion resistant than stainless steel 304. This fitting meets standards ANSI B31.1 and B1.20.1 for quality assurance.

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).
