UPVC Union

Union is a type of pipe fitting used in piping systems to connect two pipes together while allowing for easy disassembly. 

Unlike glued or solvent-welded joints, a union can be unscrewed, making it useful for maintenance, repairs, or modifications without cutting the pipe.


Advantages of Unions:

Easy Maintenance – Can be opened without cutting pipes.

Leak-proof – Sealed with a gasket or O-ring.

Chemical & Corrosion Resistant – Ideal for aggressive fluids.

Lightweight & Durable – Unlike metal unions, uPVC won’t rust.
