The PVC-U long reducer d20-16-12 PN16 offers three-step narrowing of the flow cross-section from 20 mm through 16 mm to 12 mm in a single compact fitting. The stepwise design reduces local velocity changes and minimises pressure losses at the transition point.
A maximum working pressure of 16 bar at 20 °C allows use even in the pressure branches of filtration or hydromassage systems. PVC-U material is permanently resistant to chlorine, acids and alkalis.
Solvent-cement installation on all three socket diameters creates strong joints immediately after applying PVC adhesive. The fitting is suitable for transition nodes in pool chemistry lines, fill circuits or sensor loops.
