This is the genuine Fluidra replacement O-ring that seals the joint between the filter body and the transparent polycarbonate lid on AstralPool Cantabric sand filters. A worn or damaged O-ring is the most common cause of leaks at the top of the filter, making this a critical maintenance item for any Cantabric installation. Replacing it promptly restores a fully watertight seal and keeps your filtration system running at peak efficiency.<\/p>\n
This O-ring is designed for the AstralPool Cantabric side-outlet sand filter with a tank diameter of \u00d8750 mm, a rated flow of 22,000 l\/h, and a 2″ connection. The Cantabric range is available in multiple tank sizes (\u00d8400 mm to \u00d8900 mm); always verify your tank diameter and model before ordering, as O-ring dimensions vary across the range.<\/p>\n
Genuine Fluidra parts are manufactured to exact tolerances for the Cantabric filter’s lid groove, ensuring a reliable, long-lasting seal under pool operating pressures up to 2.5 kg\/cm\u00b2. Aftermarket alternatives may differ slightly in cross-section or compound hardness, risking premature failure or persistent leaks. Sourcing directly from an authorised Fluidra supplier guarantees part authenticity and full compatibility.<\/p>\n
Before fitting, clean the lid groove thoroughly and remove all traces of the old O-ring. Lightly lubricate the new O-ring with a silicone-based grease before seating it carefully in the groove to avoid pinching or twisting. Re-seat the transparent polycarbonate lid and tighten the ABS threaded retaining nut evenly. Check for leaks on first start-up and re-tighten if necessary.<\/p>","protected":false},"excerpt":{"rendered":"
