Stainless Steel 304 Cast Pipe Fitting, Reducing Coupling, Class 150, 1" X 1/2" NPT Female
Feature
Reducing coupling for connecting and extending pipes of different sizesFemale National Pipe Taper (NPT) threads on both ends for connecting male pipes
Made of stainless steel 304 for strength
Lower carbon content for greater resistance to corrosion
Meets standards ANSI B1.20.1 and ISO 49 for quality assurance
Description
The Merit Brass reducing coupling is a class 150 stainless steel 304 cast pipe fitting with female National Pipe Taper (NPT) threads on both ends for connecting male pipes. This reducing coupling has one end that is smaller than the other for connecting different sizes of pipes going in the same direction. It has NPT threads for creating tighter seals than straight threads and is made of stainless steel 304 for higher corrosion resistance than 302 grade steel. This class 150 reducing coupling meets standards ANSI B1.20.1 and ISO 49 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure.
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).
