This is the genuine Fluidra screw set designed to secure the multiport valve fixing ring on the AstralPool Aster laminated sand filter (\u00d8750 mm \/ 21,000 l\/h, 2″ outlet with top-mount selector valve). The fasteners clamp the fixing ring firmly against the filter tank, ensuring a leak-free, pressure-rated connection between the valve and the filter body. Replacing worn or corroded screws with the correct OEM hardware is essential to maintaining a safe and watertight seal under operating pressure.<\/p>\n
This screw set is a direct spare part for the Fluidra AstralPool Aster laminated sand filter with a tank diameter of \u00d8750 mm, a flow rate of 21,000 l\/h, 2″ connections, and a top-mount 6-way multiport selector valve. It is not interchangeable with smaller Aster filter diameters (e.g. \u00d8600 mm or below) or side-mount valve configurations \u2014 always verify your filter model and valve type before ordering.<\/p>\n
Genuine Fluidra fasteners are manufactured to the exact thread pitch, material grade, and torque specification required for the valve fixing ring. Using non-OEM screws risks stripping the plastic ring, uneven clamping force, and leaks under pool operating pressure \u2014 which can reach up to 2.5 kg\/cm\u00b2 on these filters. Sourcing from poolsparthub.com guarantees you receive authentic Fluidra parts with full traceability.<\/p>\n
When fitting this screw set, ensure the fixing ring is correctly seated and that the companion ring gasket (sold separately, ref. 4404260106) is in good condition. Tighten the screws evenly in a cross pattern to apply uniform clamping force around the full circumference of the valve port. Always isolate and depressurise the filter system before carrying out any valve or ring maintenance.<\/p>","protected":false},"excerpt":{"rendered":"
