The flat PVC-U stub flange with a diameter of 140 mm is suitable for flanged connections on larger pipework, typically in commercial pools or aquaparks. It forms a solid seating surface for the gasket and allows the tightening forces of the flange bolts to be transferred safely.
The 140 mm diameter is used in high-flow pipework, such as the main suction and discharge branches of filtration circuits. As a material, PVC-U provides a significantly longer service life than iron or galvanized alternatives in an environment with chemically treated water.
The precise manufacture of the stub flange guarantees safe installation without the need for additional adjustments. We recommend combining it with an EPDM flange gasket for optimum resistance to pool chemicals.
