UPVC Union

Quick-Disconnect Fitting for Easy Maintenance

This fitting allows fast disconnection and reconnection of pipes. It has two fittings and a locking nut. The seal comes from an O-ring and threaded locking mechanism. You do not need solvent cement for this connection. Installation and removal are both quick and simple. This makes it perfect for locations needing frequent maintenance. You will use it at water treatment equipment connections, chemical filter replacement points, and pump inlet and outlet lines. Any location with regular service needs benefits from this fitting. Our unions use precision injection molding. Threads are accurate. The O-ring groove is properly designed.

The seal is reliable after locking. No leakage occurs when properly tightened. We have 10 injection molding machines and a 4-person R&D team. We can develop different sizes and seal configurations. Each union is assembly-tested and seal-checked before shipment. We have exported these to Vietnam, Turkey, and Thailand. Customer feedback confirms they are easy to use and seal well. We supply complete spare parts including O-rings and lock nuts. This makes maintenance simple for your team.
