AstralPool - Union Fitting 50 mm for Colusa Pump - 4405010774

AstralPool – Union Fitting 50 mm for Colusa Pump

This genuine AstralPool 50 mm union fitting is the official replacement hydraulic connector for the Colusa pump range. Installed at position 6 in the Fluidra exploded view, it forms the watertight threaded union that joins the pump port to the 50 mm pool pipework, enabling leak-free circulation and straightforward disconnection for servicing. Sourced directly from Fluidra, it meets the original design tolerances of the Colusa pump.

Compatibility

This union fitting is designed specifically for the AstralPool Colusa pump (parent SKU 70577), which is available in outputs ranging from 0.5 HP to 3 HP in both single-phase and three-phase configurations. It connects to standard 50 mm pressure PVC pipework. Always cross-reference your pump’s model number and the official Fluidra exploded view (position 6) before ordering to confirm fitment.

Why Genuine Matters

Genuine AstralPool parts are manufactured to exact OEM specifications, ensuring a precise fit, reliable pressure rating, and long service life in chlorinated and salt-water pool environments. Aftermarket fittings risk mismatched thread tolerances or inferior materials that can lead to leaks and premature failure. This part carries AstralPool’s full quality guarantee as a Fluidra original spare.

Installation

The union fitting is designed for straightforward hand-tightening with a standard wrench for final torque — no special tools are required. Always isolate the pump from the power supply and relieve system pressure before removing or fitting any hydraulic connections. If you are not confident working with pool plumbing, we recommend engaging a qualified pool technician to complete the installation.
