Pentair QuikSkim Venturi Nozzle | 516478 Calcium Hardness and programmable color shows thatThe Pentair QuikSkim Venturi Nozzle (516478) is the OEM replacement nozzle for the QuikSkim surface skimming system. The venturi nozzle is the functional core of the QuikSkim unit, using a pressurized water jet to create suction that draws surface debris toward the skimmer intake. When the nozzle is worn, cracked, or clogged beyond cleaning, surface skimming performance drops noticeably this direct replacement restores the system to factory operation.
