Fluidra - Multiflow Return Fitting Ball, Nut & Bush – Panel Pool Spare

Fluidra – Multiflow Return Fitting Ball, Nut & Bush – Panel Pool Spare

This genuine Fluidra AstralPool spare kit contains the Multiflow ball, retaining nut, and bush — the core internal components of the AstralPool Multiflow return inlet fitting designed for panel-wall pools. Together these three parts control the direction and flow rate of filtered water as it re-enters the pool, and they are the components most subject to wear or accidental damage during routine maintenance.

Compatibility

This kit is a direct replacement for the ball, nut, and bush assembly found in the AstralPool Multiflow return inlet fitting for panel pools — a fitting specifically engineered for pool panels with a wall thickness of 10 to 15 cm, using a Ø 50 mm solvent-weld pipe connection. Always verify your existing fitting model and panel thickness before ordering to confirm fitment.

The Multiflow System

The Multiflow ball is supplied pre-marked with three selectable orifice diameters — Ø14 mm, Ø20 mm, and Ø25 mm — allowing the installer to punch out the chosen diameter at the time of installation and fine-tune the flow rate to suit the pool’s circulation requirements. Maximum recommended flow rates at 4 m/s are: Ø14 = 2.2 m³/h, Ø20 = 4.5 m³/h, and Ø25 = 7.0 m³/h, in accordance with EN 13451-1.

Why Genuine Matters

As an official Fluidra spare part, this kit is manufactured to the exact tolerances of the original fitting, ensuring a leak-free seal and smooth ball articulation. Generic alternatives may not match the pre-marking positions or thread dimensions, risking poor flow control or water loss. Replacing these components with genuine parts protects your liner and maintains safe pool hydraulics.
