These PVC drainage pipe 4-way connectors solve the problem of branching drain lines cleanly — whether you're roughing in a bathroom, tying together a sub-floor drainage grid, or extending an outdoor stormwater network.\u003c\/p\u003e\n\u003cp\u003eEach fitting is molded from rigid PVC (polyvinyl chloride), a material well-suited to non-pressure drainage applications. Available in three junction geometries — Plane 4-Way (flat cross), Oblique 4-Way (angled branch), and Steric 4-Way (offset\/3D branch) — and in model sizes ranging from 50×50mm (~2\"×2\") up to 200×200mm (~8\"×8\"), with a full range of reducer combinations (e.g., 110×50mm, 160×110mm) to match existing pipe runs without additional reducers.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include residential sub-floor drain manifolds where multiple fixture drains converge, commercial kitchen floor drain networks requiring cross-junction fittings, and outdoor stormwater or irrigation drainage systems needing a compact 4-way split. The reducer variants are especially useful when tying a smaller branch line into a larger main drain — a common scenario in bathroom remodels and laundry room rough-ins.\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 non-pressure gravity drainage applications.
