What is a Union Threaded Fitting?
A Union Threaded Fitting is a pipe connector composed of a nut and a joint, used to connect two pipes. Its key feature is that it allows disassembly without rotating the pipes, facilitating easy maintenance or equipment replacement. It offers good sealing performance and can be reused multiple times.
Maintenance Tips
Regular Inspection: Check for leaks or looseness and tighten as needed.
Avoid Over-tightening: Hand-tighten first, then gently tighten with a tool. Over-tightening may damage the threads.
Rust and Corrosion Prevention: Keep the surface dry and avoid contact with corrosive substances.
Seal Ring Care: If a gasket is used, regularly check for aging or deformation and replace if necessary.
Disassembly Caution: Protect the threads during disassembly to prevent damage. Clean the threads thoroughly before reassembly to ensure smooth connection.
