The reduced 90° PVC tee d90×63×90 combines a 90 mm through-bore with a d63 branch socket; the small difference in cross-sections minimises hydraulic losses and allows full flow even in the branch line.
This fitting is ideal for branching the main circulation circuit of large pools, where a considerable volume of water passes through the branch line (e.g. to a heat exchanger or counter-current unit).
The PVC-U material with PN 10 meets the demands of pool hydraulics as well as chemically aggressive operations; the lower weight compared to metal facilitates handling during installation in trenches or service shafts.
For a reliable joint at the d90 diameter, it is essential to use certified adhesive and primer; after installation, allow the joint to cure for at least 2 hours before starting the pressure test.
