A PPR cross joins four PPR pipes at one point.
It feeds two branches from one point on the run. Therefore, it saves space in compact manifolds.
What is a PPR cross?
A PPR tee joins three PPR pipes in a T shape, so a branch can leave the main line. A cross joins four. Threaded tees have a brass thread on the branch for a tap, gauge or valve.
Tees are fused like other PPR fittings. As a result, each branch joint is leak-free and rust-free for the life of the system.

Key terms explained
