The offset bore keeps the bottom of both pipes flush, preventing sediment traps and allowing full drainage, which is exactly what drain, waste, and vent (DWV) runs demand.\u003c\/p\u003e\n    \u003cp\u003eEach bushing is molded from rigid white PVC (polyvinyl chloride), the same material used in residential and light-commercial plumbing systems worldwide. The eccentric bore is machined off-center so the flat side of the fitting aligns flush with one side of the pipe. Available in six size combinations — 75×50mm (~3\"×2\"), 110×50mm (~4\"×2\"), 110×75mm (~4\"×3\"), 160×110mm (~6\"×4\"), 200×110mm (~8\"×4\"), and 200×160mm (~8\"×6\") — covering the most common DWV reduction steps. Wall thickness and socket depth follow standard PVC DWV tolerances for a secure solvent-weld joint.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include horizontal drain-line reductions where gravity flow must be maintained without air locks, bathroom and kitchen rough-in plumbing where pipe sizes step down before connecting to fixtures, and retrofit upgrades where an existing larger-diameter stack needs to accept a smaller branch line without cutting into finished walls.\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 DWV pipe and fittings.

An eccentric reducer offsets the bore so one flat side of both pipes aligns flush. In horizontal drain lines, the eccentric design keeps the pipe bottom level, preventing air pockets and ensuring complete gravity drainage — making it the correct choice for DWV applications.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eHow do I choose the right size for my pipe run?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eMatch the larger socket to your existing (larger) pipe's outer diameter and the smaller socket to the branch or downstream pipe. For example, if you are stepping down from a 110mm stack to a 50mm branch, select the 110×50mm bushing. Measure your pipe OD before ordering — nominal pipe sizes and actual ODs can differ by a few millimeters depending on the standard used in your region.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eIs PVC strong enough for drain line use?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eYes. Rigid PVC is the industry-standard material for residential DWV systems. It handles typical household drain temperatures (up to approximately 60°C \/ 140°F for short durations), resists common household chemicals, and does not corrode or degrade in buried or concealed installations. It is not rated for continuous hot-water pressure lines — for those applications, CPVC or copper is recommended.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eWill this bushing resist corrosion and chemical exposure?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003ePVC is inherently corrosion-resistant and non-reactive with most household drain chemicals, including common drain cleaners at normal dilutions.
