AstralPool - Pump Pre-filter Lid O-Ring - SP-04-0074

AstralPool – pump pre-filter lid O-ring

This is a genuine AstralPool replacement O-ring designed to seal the pre-filter lid to the pump body. It creates an airtight, watertight barrier between the lid and the pump housing, ensuring the pump maintains prime and operates at full efficiency. Replacing a worn or perished O-ring is one of the most common and cost-effective pool pump maintenance tasks.

Why your pump needs this

A damaged or aged lid O-ring is the leading cause of pool pumps losing prime or failing to prime altogether — even a slight gap allows air to enter the suction side and disrupt flow. Symptoms include air bubbles in the return jets, a noisy pump, or a pump that runs dry. Swapping this small rubber seal can resolve all of these issues instantly, avoiding costly service calls or pump damage.

Compatibility

This O-ring is a genuine AstralPool spare part (SKU SP-04-0074) intended for use with AstralPool pump pre-filter lids. Always cross-reference your pump model and current lid part number against the Fluidra parts diagram or consult a qualified pool technician to confirm fitment before ordering.

Installation & maintenance

Installation requires no special tools — simply remove the old O-ring from its groove, clean the seating channel, and seat the new ring. Always lubricate the O-ring with a silicone-based grease only; petroleum-based greases will swell and degrade the rubber. AstralPool recommends inspecting the lid O-ring every three months as part of routine pump maintenance.
