PVC Water Pipe Fittings Equal Cross 4-way Connectors Socket Solvent Weld 20-90mm

"4-Way" means the fitting has four socket ports arranged in a cross (plus-sign) pattern — two ports on one axis and two on the perpendicular axis. "Equal" means all four ports share the same inner diameter, so all connected pipes must be the same size. No reducers are needed when all branch lines match the fitting’s inner diameter.

Select the inner diameter that matches your pipe’s nominal size: 20mm (~¾"), 25mm (~1"), 32mm (~1¼"), 40mm (~1½"), 50mm (~2"), 63mm (~2½"), 75mm (~3"), or 90mm (~3½"). Measure the outer diameter of your existing pipe and cross-reference with standard PVC pipe OD charts to confirm the correct nominal size. All four ports will be the same size, so all connected pipes must match.

Colour choice is typically driven by system convention or site preference. Blue is commonly used in potable cold-water supply systems where colour-coding by service type is standard practice. White and Gray are widely used in irrigation, drainage, and general water pipe systems. All three colours are the same PVC material and perform identically — colour does not affect pressure rating or chemical compatibility.

These connectors are molded from rigid PVC to pressure fitting dimensional tolerances and are suitable for pressurized water pipe applications including irrigation and cold-water supply. Always verify the specific pressure rating for your chosen size against your system’s working pressure requirements. For hot-water lines above approximately 60°C / 140°F, CPVC or other heat-rated materials are recommended.

Rigid PVC is inherently corrosion-resistant and does not react with potable cold water, irrigation water, or most common water treatment chemicals at standard concentrations. It will not rust, scale, or pit under normal operating conditions, making it a long-lasting choice for both buried and above-ground water pipe systems.

Yes. PVC equal cross 4-way connectors are widely used in modular pipe framework applications — including shelving, greenhouse frames, display structures, and furniture — where a rigid four-direction planar node is needed. In non-pressure structural applications, you can use PVC cement for a permanent bond or leave joints dry-fit for a reconfigurable structure.

Cut all pipe ends square and deburr the cut edges. Dry-fit all four pipes into the cross connector to confirm alignment before cementing — this is critical with a 4-way fitting since all ports must align simultaneously. Apply PVC primer to both the pipe end and the socket, then apply PVC cement to both surfaces. Insert the pipe with a slight twist and hold for 30 seconds. Work port by port and allow each joint to cure fully per the cement manufacturer’s instructions before pressurizing the system.

For a single cross-node or repair, 1 piece is sufficient. For irrigation grids or modular frameworks with multiple cross-nodes of the same size, the 5, 10, or 20-piece packs offer a lower per-unit cost and ensure you have spares on hand. The 2-piece option suits small two-node builds or when a backup is needed for a critical connection point.
