Which term describes a fitting used to connect two pipe sections with a threaded joint?

• A. Elbow
• B. Cap
• C. Union
• D. Tee

Answer: (C)

Connecting two pipe sections with a threaded joint and allowing that connection to be taken apart easily is what a union is designed to do. A union uses two threaded ends and a central nut that clamps them together, letting you disconnect without cutting the pipes for maintenance or replacement. An elbow only changes direction, a cap seals the end of a pipe, and a tee creates or joins branches, none of which are built for easy disassembly of a threaded connection. So the fitting described is a union.
