These PVC drainage pipe eccentric reducer adapter connector fittings are designed for homeowners, plumbers, and DIY renovators who need a clean, leak-free transition between two different pipe sizes while keeping the pipe bottoms flush — preventing sediment buildup and maintaining consistent flow.\u003c\/p\u003e\n    \u003cp\u003eEach fitting is manufactured from rigid white PVC, engineered for drainage and waste applications. Available in four size combinations — 75×50mm (~3\"×2\"), 110×50mm (~4\"×2\"), 110×75mm (~4\"×3\"), and 160×110mm (~6\"×4\") — these eccentric reducers accommodate the most common residential and light commercial drain pipe transitions. Wall thickness and socket depth are sized to match standard DIN\/AS\/NZS drainage pipe OD tolerances.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include bathroom and kitchen drain stack reductions, laundry waste line transitions, underground drainage eccentric reducer connections, and PVC soil pipe adapter fittings for renovation projects where pipe invert levels must be maintained.\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    Compatible with standard PVC drainage pipe (DIN 19531 \/ AS 1260 \/ BS EN 1401 equivalent OD tolerances).

An eccentric reducer offsets the centerlines so that one side (typically the bottom\/invert) remains flat and flush. This is critical for horizontal drain runs because it prevents a low pocket where water and solids can pool, maintaining consistent self-draining flow.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eHow do I choose the right size model?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eMeasure the outer diameter (OD) of both pipes you need to connect — the larger pipe and the smaller pipe. Match those measurements to the model size listed (e.g., 110×75mm means the larger socket fits 110mm OD pipe and the smaller socket fits 75mm OD pipe). If you are unsure, check the pipe markings or use a caliper to measure the OD directly.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eCan this fitting be used for underground drainage?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eYes.
