This genuine Fluidra fixing ring is the retaining collar that clamps and secures the 2″ top-mount multiport valve to the filter tank head, creating a stable, pressure-tight connection. It is a direct original replacement part for the AstralPool Aster laminated sand filter (\u00d8750 mm, 21,000 l\/h) equipped with a 2″ top-mount selector valve. Without an intact fixing ring, the multiport valve cannot be held safely in position, risking leaks or valve movement under operating pressure.<\/p>\n
This fixing ring is designed for the Fluidra AstralPool Aster sand filter with a \u00d8750 mm tank body, a maximum flow rate of 21,000 l\/h, and a 2″ outlet fitted with a top-mount multiport valve. Always verify your filter model and valve size before ordering, as visually similar rings for 1\u00bd” valves or side-mount configurations are not interchangeable.<\/p>\n
As an original Fluidra spare part, this fixing ring is manufactured to the exact dimensional tolerances of the assembly, ensuring the multiport valve seats correctly and that full operating pressure of up to 2.5 kg\/cm\u00b2 is safely contained. Aftermarket alternatives may differ subtly in thread pitch or diameter, leading to poor seating, leaks, or premature failure.<\/p>\n
Depressurise and drain the filter before removing the old ring. Inspect the valve neck and tank head for damage or debris, then seat the new ring and engage it evenly around the valve collar, tightening uniformly to avoid cross-threading. Reassemble, restore pressure slowly, and check for leaks before returning the filter to service.<\/p>","protected":false},"excerpt":{"rendered":"
