PVC Pressure Reducing Coupling 25mm x 20mm (1" x 3/4") used to join 25mm and 20mm PVC pressure pipe in a straight line. The 25mm socket suits PVC pressure pipe with a 33.6mm outside diameter, while the 20mm socket suits pipe with a 26.8mm outside diameter.
Both sockets fit over their matching PVC pressure pipe and are joined using PVC priming fluid and pressure-rated solvent cement. This joining method is known as a solvent weld joint, or SWJ.
Manufactured from rigid PVC-U, the reducing coupling is suited to residential, commercial and agricultural irrigation, garden and landscape watering, domestic and rural water supply, pump systems, pool and spa equipment, general water transfer and compatible PVC pressure pipework.
