Plumbers, contractors, and serious DIYers working on bathroom waste lines, kitchen drain stacks, or outdoor drainage networks need a connector that handles oblique branch angles without leaking under sustained load.\u003c\/p\u003e\n\u003cp\u003eThese PVC 4-way oblique equal reducer drainage pipe connectors are moulded from rigid PVC compound and feature solvent-weld socket ends for a permanent, leak-free bond. Inner diameter options span 50×50 mm (approx. 2×2 in) through 160×160 mm (approx. 6.3×6.3 in), with rectangular cross-section variants (e.g. 75×50 mm, 110×75 mm) available for non-square duct runs. Wall thickness is consistent with standard DIN\/AS drainage schedules across all sizes.\u003c\/p\u003e\n\u003cp\u003eTypical applications include multi-branch floor drain manifolds in wet rooms, four-way junction boxes in underground stormwater drainage, rectangular downpipe adapters on commercial façades, and split-run waste connections behind vanity units — all scenarios where a PVC 4-way oblique reducer drainage fitting eliminates the need for multiple separate elbows and tees.\u003c\/p\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 standard PVC drainage pipe systems.
