Plumbers, facilities managers, and DIY renovators working on drainage, irrigation, or water supply lines often reach for a standard concentric reducer only to find it traps air or misaligns with floor-level runs. These PVC eccentric reducer connectors solve that problem by offsetting the centreline so the flat side of both sockets aligns on one plane.\u003c\/p\u003e\n\u003cp\u003eEach connector is moulded from rigid PVC and sized to metric inner diameters. Available transitions are 75mm × 50mm (~3\" × 2\"), 110mm × 50mm (~4\" × 2\"), 110mm × 75mm (~4\" × 3\"), and 160mm × 110mm (~6\" × 4\"). The socket depth is proportional to the pipe diameter, typically 38–65mm, and the fitting is designed for solvent-weld (cement) jointing to standard metric PVC pipe.\u003c\/p\u003e\n\u003cp\u003eTypical applications include horizontal drainage runs where gravity flow must be maintained without air pockets, pump discharge lines where pipe size steps down after the pump outlet, and irrigation manifold assemblies where branch lines reduce from a main header. These fittings are also used in commercial HVAC condensate drainage and grey-water recycling systems where eccentric offset is specified by the engineer.\u003c\/p\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n  \u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n  Compatible with metric PVC pressure and drainage pipe to ISO 1452 \/ EN 1329 standards.
