Fluidra - Gaskets & Nut Set Ø50 mm – PTK 1200 Arm Filter (Ø650–800)

Fluidra – Gaskets & Nut Set Ø50 mm – PTK 1200 Arm Filter (Ø650–800)

This genuine Fluidra service kit supplies the replacement gaskets and retaining nut sized for Ø50 mm connections on the internal arm collector assembly of the PTK 1200 mm sand filter range. Keeping these sealing components in good condition is essential to prevent internal bypassing of unfiltered water and to maintain the filter’s rated performance.

Compatibility

Designed specifically for the Fluidra PTK 1200 mm arm-type sand filters fitted to tanks with diameters of 650 mm and 800 mm (Astralpool/Fluidra models 04949 and 04972). These large commercial fibreglass filters use an arm collector system with Ø50 mm pipe connections internally, and this kit provides the correct gaskets and nut for those joints. Always verify your filter model number before ordering.

Why genuine matters

Fluidra specifies EPDM gaskets throughout these filters for reliable chemical resistance and long service life in chlorinated and saline pool water. A genuine replacement nut ensures the correct torque can be applied without stripping threads, maintaining a leak-free seal under the filter’s operating pressure. Non-genuine parts risk premature failure and potential water bypass inside the vessel.

Installation

Installation requires draining and depressurising the filter before opening the inspection manhole to access the arm collector. The worn gasket and nut should be removed, mating surfaces cleaned, and the new components fitted and tightened to the manufacturer’s specification. A qualified pool technician is recommended for this work on commercial filter installations.
