These PVC reducer sockets are designed for DIYers and trade plumbers who need a dependable, solvent-weld transition fitting that seats flush and holds under continuous flow.\u003c\/p\u003e\n\u003cp\u003eEach fitting is moulded from rigid uPVC and is available in two configurations — Concentric Reducer Sockets (where both pipe axes share the same centreline) and Eccentric Reducer Sockets (where one side of the socket sits flat, keeping the pipe invert level). Sizes span 75 mm × 50 mm (~3\" × 2\") up to 400 mm × 315 mm (~16\" × 12\"), covering the most common metric pipe diameters used in residential and light-commercial plumbing.\u003c\/p\u003e\n\u003cp\u003eTypical applications include connecting 110 mm soil pipes to 75 mm branch lines in bathroom drainage, stepping down 160 mm underground drainage to 110 mm internal stacks, and reducing 315 mm or 400 mm large-bore stormwater mains to smaller distribution pipes in commercial fit-outs or civil drainage projects.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for metric uPVC pressure and drainage pipe conforming to common DIN\/EN standards.
