Kompatibilität

This O-ring is the correct part for the AstralPool Counterflow Pump 5.5 HP III (SKU 65549). According to the official Fluidra spare parts catalogue, the same O-ring (4405010377) is also used across a number of other AstralPool pump families, including selected Maxim, Shark, and Kivu pump models. Always cross-reference the exploded view diagram for your specific pump model before ordering.

Warum Echtheit zählt

Genuine AstralPool O-rings are manufactured to exact dimensional and material tolerances for their respective pumps, ensuring a reliable seal under continuous pool operating pressures. Aftermarket substitutes may differ in durometer or diameter, leading to premature failure or persistent leaking. Fitting an authentic part protects your pump warranty and gives you confidence in a long service life.

Installation

Before fitting, clean the O-ring groove thoroughly to remove any debris or residue from the old seal. Lightly lubricate the new O-ring with a silicone-based grease (never petroleum-based) before seating it evenly in the groove. Refer to position 4 in the official Fluidra exploded view for your pump model to confirm correct placement, and always isolate the pump from the power supply before starting any maintenance work.
