The three-piece union d90 is a standard dismountable connection for PVC-U pressure pipework with an outer diameter of 90 mm, designed for solvent welding at both ends.
The dismountable three-piece design (nut, flanges and central body) allows quick removal of the pump, filter or valve without the need to cut the pipework.
The PVC-U material withstands chlorinated water, common pool chemicals and UV radiation in outdoor installations.
Sealing is achieved by an O-ring of EPDM or NBR rubber, which guarantees long-term tightness with no water leakage.
Suitable for all standard distribution lines of filtration and circulation equipment in recreational and public pools.
