PVC 4-Way Cross Equal Reducer Drainage Pipe Connectors Tube Fittings Adapters

Choose an equal cross when all four pipes in your layout share the same diameter — for example, a 110×110 mm cross where every branch is a 110 mm drain line. Choose a reducer cross when two of the ports need to transition to a smaller pipe — for example, a 160×110 mm fitting where the main run is 160 mm and the two branch lines are 110 mm. Using a reducer cross eliminates the need for separate reducer couplings, keeping the junction compact and leak points to a minimum.

No. These are drainage-grade PVC cross fittings designed for gravity-flow drainage, waste, and stormwater applications. They are not rated for pressurized supply lines. For pressure applications, you would need Schedule 80 or pressure-rated PVC fittings with the appropriate pressure rating stamped on the fitting. Using drainage fittings under sustained pressure can result in joint failure.

Use a standard PVC solvent cement formulated for drainage or all-purpose PVC pipe. For larger diameters (110 mm and above), a medium- or heavy-bodied cement is recommended to ensure full socket coverage before the cement sets. Always apply PVC primer first to clean and soften the mating surfaces, then apply cement to both the pipe spigot and the fitting socket, and push together with a quarter-turn twist. Hold for 30 seconds and allow the joint to cure per the cement manufacturer's instructions before running water.

Yes. Rigid PVC is widely used in underground drainage applications. It resists soil moisture, mild soil acids, and common fertilizer chemicals. For burial installations, ensure the trench is properly bedded with compacted granular material to prevent point loading on the fitting body, and confirm that the burial depth meets local code requirements for the pipe diameter in use. PVC is not affected by corrosion, making it a long-lasting choice for below-grade drainage.

Measure the outer diameter (OD) of your existing pipe, then cross-reference it against the nominal inner diameter of the fitting. For standard PVC drainage pipe, the fitting socket inner diameter is sized to accept the pipe's OD with a close slip fit. As a general guide: a 50 mm fitting socket accepts ~50 mm OD pipe (~2 in nominal), a 110 mm socket accepts ~110 mm OD pipe (~4 in nominal), and so on. If you are unsure, contact us with your pipe's OD measurement and we can confirm compatibility.

Yes, with conditions. For stormwater drainage, these fittings are well-suited — they handle the flow volumes typical of residential and light-commercial roof drainage and surface water collection. For irrigation manifolds, they work in low-pressure drip or gravity-fed systems. They are not suitable for high-pressure irrigation systems (e.g., those running above 40–60 psi). Always verify the operating pressure of your irrigation system before selecting a fitting type.

Each listing offers 1 Pcs, 2 Pcs, or 5 Pcs per order. Buying 2 or 5 pieces is cost-effective when you have multiple junction points in the same drainage layout — for example, a stormwater system with several four-way intersections, or a contractor stocking fittings for a multi-unit project. The per-unit price decreases with higher quantities, so ordering in bulk reduces both cost and the risk of running short mid-installation.
