Description
A 3/8" black steel pipe union is a threaded fitting designed to connect two sections of pipe while allowing easy disassembly for maintenance, repair, or system modifications. Unlike standard couplings, unions can be separated without rotating the connected pipe, making them ideal for serviceable piping systems.
These fittings are typically manufactured from black malleable iron or black steel and feature threaded female NPT connections with a central union nut. They are commonly used in compressed air systems, natural gas lines, fire sprinkler piping, and industrial applications requiring durable threaded joints with future service access.
