Fluidra – Filter O-Ring for AstralPool Cantabric Sand Filter Ø750 mm

Fluidra – Filter O-Ring for AstralPool Cantabric Sand Filter Ø750 mm

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.

Compatibility

This O-ring is designed for the AstralPool Cantabric side-outlet sand filter with a tank diameter of Ø750 mm, a rated flow of 22,000 l/h, and a 2″ connection. The Cantabric range is available in multiple tank sizes (Ø400 mm to Ø900 mm); always verify your tank diameter and model before ordering, as O-ring dimensions vary across the range.

Why genuine matters

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/cm². 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.

Installation

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.
