NPT Union
A union also connects two pipes, but is quite different from a coupling, as it allows future disconnection of the pipes for maintenance. These NPT Threaded Pipe Fittings Class 150# 316 stainless steel has a higher nickel content for better corrosion resistance. Use Schedule 40 or 80 stainless steel pipe for applications with air, water, and natural gas.
