Reduced 90° PVC Tee d90×75×90

The reduced 90° PVC tee d90×75×90 is among the largest standard fittings for pool and industrial distribution systems; the 90 mm through-bore with a d75 branch socket ensures minimal hydraulic losses even at high flow rates.

This configuration of diameters is suitable for systems where the branch line carries or removes a large proportion of the total flow — for example in overflow pools with powerful circulation or in industrial cooling circuits.

The PVC-U material with PN 10 certification resists chlorine, acids, alkalis and UV radiation; the absence of metal parts eliminates the risk of corrosion even when operating in aggressive media.

Installation by solvent welding requires careful preparation: degreasing, application of primer and even adhesive around the entire circumference — for diameters of 75–90 mm these steps are critical to achieving a durable, pressure-tight joint.
