PVC Pressure Reducing Coupling 100mm x 80mm (4" x 3") used to join 100mm and 80mm PVC pressure pipe in a straight line. The 100mm socket suits PVC pressure pipe with a 114.3mm outside diameter, while the 80mm socket suits pipe with an 88.9mm 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.
