AstralPool - Colusa Pump O-Ring 151.7 × 6.99 mm - 4405010772

AstralPool – Colusa Pump O-Ring 151.7 × 6.99 mm

This is the genuine AstralPool replacement O-ring (151.7 × 6.99 mm) for the Colusa pool pump, occupying position 3 in the official Fluidra exploded-view diagram. It forms a precise, watertight seal within the pump assembly, maintaining the vacuum and pressure necessary for efficient water circulation and filtration. Replacing a worn or cracked O-ring promptly prevents air ingestion, water leaks, and loss of pump prime.

Compatibility

This O-ring is designed exclusively for the AstralPool Colusa Pump (parent SKU 70579). It corresponds to exploded-view position 3, making it straightforward to identify the correct location during servicing. Always cross-reference your pump’s model code and exploded-view diagram before ordering to ensure an exact fit.

Why Genuine Matters

OEM AstralPool O-rings are manufactured to the precise dimensional tolerances required by the Colusa pump housing. An incorrect size or inferior material can result in leaks, air locks, or accelerated wear on surrounding components. Choosing a genuine part guarantees the seal performs as engineered throughout the full service life of your pump.

Installation

Remove the old O-ring, clean the seating groove thoroughly, and apply a thin layer of compatible O-ring lubricant before fitting the new seal. Avoid over-stretching during installation. While many competent pool owners can perform this swap themselves, a qualified pool technician is recommended if you are unfamiliar with pump disassembly.
