The advantage of PVC fittings is easy handling, simple installation, and chemical resistance.
The PVC-U pressure fitting is suitable for piping in filtration systems for swimming ponds, pools, ornamental ponds, fish tanks, and similar applications. The coupling with internal thread is designed for transitioning from a threaded connection to a standard PVC pipe or flexible hose. It is most commonly used for connecting equipment with external threads. Never glue the threaded connection. Use Teflon tape or sealing thread to seal the joint.
Before gluing, all joints must be thoroughly cleaned. Use Tangit or Griffon. Apply a thin layer of Tangit or Griffon adhesive to both the fitting and the pipe, then press the joints together. Allow at least 5 minutes to dry. Pool adhesives cure in 10–12 hours.
