PVC manifold for valve manifolds in swimming pool filtration circuits. It simplifies the installation of ball valves: the 3 inlet connections are male to directly glue the valves, without having to cut PVC pipes. The 3-way manifold for gluing is made of PVC, pressure PN16. Available in various sizes from Ø 50 to Ø 63. Notub system that allows direct connections between fittings and valves, thus saving a considerable amount of gluing, time and installation costs.
