PP Union

The PP Union is a high-performance detachable pipe fitting designed for easy installation and disassembly of polypropylene piping systems. Engineered from high-quality polypropylene (PP), it provides robust mechanical strength, excellent chemical resistance, and long-term durability. The union consists of two socket or threaded ends joined by a central nut, allowing for easy removal and maintenance of pipe sections without cutting or damaging the system.
