The transition between diameters 280 and 250 mm is seemingly small, but this short PVC-U reducer ensures that the hydraulic transition takes place without significant pressure loss or turbulent flow.
The pressure class PN16 and the robust wall of the fitting are a necessity for installations in industrial or public pools with powerful pumps and extensive distribution networks.
The glued design in this diameter requires expert installation, but the resulting joint is permanent, impermeable and resistant to the mechanical stress caused by operating pressures and vibrations.
