Merrit Brass 487-20 T304 1-1/4" Stainless Steel Union

 

The Merit Brass union is a class 150 stainless steel 304 cast pipe fitting with female National Pipe Taper (NPT) threads for connecting and extending two male threaded pipes. The union has three pieces and includes a threaded connection that can be screwed or unscrewed to connect or disconnect pipes more easily than couplings. It has NPT threads on both ends for creating tighter seals than straight threads. Made of stainless steel 304, the lower carbon content of this fitting ensures higher corrosion resistance than 302 grade steel. This class 150 fitting meets standards ISO 49 and ANSI B1.20.1 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.
