50-200mm PVC Drainage Pipe 4-Way Equal Reducer Connector Adapter Drain Fittings

The Plane 4-Way is a flat cross junction — all four ports exit in the same plane, ideal for horizontal drain runs that branch left, right, and straight. The Oblique 4-Way has one or more ports at an angle, which helps maintain drainage slope on branching lines. The Steric 4-Way is an offset 3D junction suited for situations where pipes approach from different vertical planes, such as combining a floor drain with a wall drain in the same fitting. Match the type to your pipe routing geometry before ordering.

No. These are designed for non-pressure gravity drainage applications only. Rigid PVC drainage fittings are not rated for pressurized water supply lines or continuous hot water above approximately 60°C (140°F). For hot water or pressure applications, use CPVC or other pressure-rated fittings.

PVC has good resistance to most household drain waste, including soaps, detergents, dilute acids, and mild alkalis. However, concentrated solvents or highly aggressive industrial chemicals can degrade PVC over time. For standard residential drain waste — including kitchen, bathroom, and laundry — these fittings are well-suited.

The model dimensions (e.g., 110×110mm) refer to the nominal pipe diameter the fitting is designed to accept. Always verify the actual outside diameter (OD) of your existing pipe before ordering, as pipe schedules and standards can vary. If you are unsure, measure your pipe OD directly and contact us to confirm compatibility.

Installation uses standard PVC solvent cement (not included). Clean and dry both the pipe end and fitting socket, apply primer if required by local code, brush on PVC cement, insert the pipe with a slight twist, and hold for 30 seconds. No special power tools are required. A pipe cutter or hacksaw, deburring tool, and applicator brush are sufficient for most installations.

Yes — that is exactly what the reducer model variants are for. For example, the 110×50mm variant allows a 50mm branch line to connect into a 110mm main drain run at the same junction, eliminating the need for a separate reducer coupling. Select the model that matches your main pipe size on the larger ports and your branch pipe size on the smaller port.

PVC is generally suitable for underground and outdoor drainage use in non-pressure gravity systems. For buried installations, ensure the fitting is rated for the burial depth and soil load in your application, and that all joints are fully cured before backfilling. Prolonged UV exposure above ground can cause surface degradation over time — paint or shield exposed sections if needed.
