PPR Cross 4-Way Pipe Fitting

PPR Cross 4-Way Pipe Fitting is a more specialized connector, used where a single junction needs to distribute or collect flow in four directions rather than the three handled by a standard tee. With four sockets arranged around a central body, this fitting lets installers build a compact distribution node without combining separate tees or elbows.
Because it combines what would otherwise take two separate tee fittings, the cross fitting can reduce both the number of joints in a system and the space a junction occupies, which can be useful in crowded mechanical rooms or underfloor heating manifolds. Each of the four ports is fused to its connecting pipe using the same heat-fusion process as other fittings in the range, and the wall sections around the central junction are generally designed to handle the combined stress of four connections meeting at one point.
Like other fittings in the range, the cross is typically produced from PP-R80/PP-R100 resin. Its symmetrical geometry means it can be installed with any of the four ports as the inlet, which gives some flexibility when laying out manifold-style networks.
The cross fitting is less commonly used in basic residential plumbing than sockets, elbows or tees, but is a useful component for more complex distribution layouts; available sizes are typically narrower than for the other fittings in the range and should be confirmed directly with the supplier.
