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.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).Merit Brass manufactures pipe nipples following ISO 9001 standards for quality assurance. The company, family-owned since 1937 and headquartered in Cleveland, OH, distributes pipe fittings in the United States and Canada. ## Features - Union for connecting and extending two male pipes - Female National Pipe Taper (NPT) threads on both ends for connecting two male threaded pipes - Made of stainless steel 304 for greater strength than 302 grade steel - Low carbon content for greater resistance to corrosion - Meets standards ISO 49 and ANSI B1.20.1 for quality assurance ## Product Details - **Size:** 3/8 Inch - **Material:** Stainless Steel - **Brand:** Merit Brass - **Connector Type:** Union - **Exterior Finish:** Brass - **Thread Type:** NPT - **Item Weight:** 0.01 Ounces - **Number of Pieces:** 3 - **Global Trade Identification Number:** 10671404096462 - **Manufacturer:** Merit Brass ## Images ![Stainless Steel 304 Cast Pipe Fitting, Union, Class 150, 3/8" NPT Female - Image 1](https://m.media-amazon.com/images/I/815hk9P9e0L.jpg) ![Stainless Steel 304 Cast Pipe Fitting, Union, Class 150, 3/8" NPT Female - Image 2](https://m.media-amazon.com/images/I/912TdqgvcCL.jpg) ![Stainless Steel 304 Cast Pipe Fitting, Union, Class 150, 3/8" NPT Female - Image 3](https://m.media-amazon.com/images/I/91XGZr2VaFL.jpg) ![Stainless Steel 304 Cast Pipe Fitting, Union, Class 150, 3/8" NPT Female - Image 4](https://m.media-amazon.com/images/I/71VJ0gfNH9L.jpg) ## Available Options This product comes in different **Size, Number Of Items** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ gas unions *by K***. on April 14, 2021* Bought 2 unions. They were different styles. Worked. ### ⭐⭐⭐⭐⭐ What can you say about a pipe union? It ... *by D***H on March 27, 2015* What can you say about a pipe union? It was 1/2" NPT (as advertised) and it mated properly with all my other 1/2" NPT fittings. Oh, and it appeared to be made from 304 stainless (also, as advertised). ### ⭐ Impossible to stop leaks. *by D***H on June 28, 2021* Junk. I put so much Teflon tape to stop the leaks and failed. No matter how much I tighten it, how much Teflon tape was used it still leaks. Only 45psi water.
