PVC Pressure Reducing Coupling 100mm x 50mm (4" x 2") used to join 100mm and 50mm PVC pressure pipe in a straight line. The 100mm socket suits PVC pressure pipe with a 114.3mm outside diameter, while the 50mm socket suits pipe with a 60.4mm 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 commercial and agricultural irrigation, rural water supply, pump systems, pool and spa equipment, general water transfer and compatible PVC pressure pipework.
