PVC CAT8 Pressure Reducing Coupling Joiner WaterMarked (Cat No. 8)

The PVC CAT8 Pressure Reducing Coupling Joiner is a WaterMarked, high-quality fitting designed to create a secure transition between different pipe sizes within a PVC pressure system. Manufactured from strong, corrosion-resistant white PVC, this coupling delivers reliable long-term performance in potable water, irrigation and commercial plumbing networks.

Its precision-moulded solvent-weld sockets provide a permanent, leak-free connection once primed and glued, allowing larger pipes to be safely reduced to smaller diameters without compromising pressure integrity. Easy to install and fully compliant with Australian WaterMark standards, the CAT8 reducing coupling is essential for system modifications, extensions and new installations requiring an accurate size reduction.
