AstralPool - O-Ring 60 × 8 mm Filter Seal - SP-04-0253

AstralPool – O-ring 60 × 8 mm filter seal

This genuine AstralPool O-ring (60 mm inner diameter, 8 mm cord thickness) is a precision rubber sealing ring used in AstralPool swimming pool filters. It maintains a watertight seal at critical connection points, preventing leaks and keeping the filtration system operating at the correct pressure.

Compatibility

This O-ring is a genuine AstralPool spare part (Fluidra catalogue reference 4404040115) designed for use in AstralPool filter ranges including the Aster series. Always verify the part number against your filter’s exploded-view diagram before ordering to ensure an exact fit for your specific model and production year.

Why genuine matters

Genuine AstralPool O-rings are manufactured to the precise dimensions and rubber compound required by the original equipment, ensuring a reliable, long-lasting seal in chlorinated pool water. Aftermarket seals of incorrect hardness or diameter can deform under pressure, leading to persistent leaks and premature failure.

Installation

Before fitting, clean the seating groove thoroughly and remove any remnants of the old O-ring. Lightly lubricate the new O-ring with a silicone-based grease before seating it evenly in the groove — avoid pinching or twisting the ring. Reassemble the filter connection and check for leaks once the system is returned to pressure.
