Fluidra - External Discharge Port Nut for Atlas Sand Filter

Fluidra – External Discharge Port Nut for Atlas Sand Filter

This is the genuine Fluidra external discharge port nut (screw) for the Atlas sand filter series. It forms part of the 2½” sand discharge assembly at the base of the filter tank, securing the outlet port and maintaining a watertight seal during backwash and drainage operations.

Compatibility

Designed as an original spare part for the Fluidra Atlas sand filter range (models 36596, 36597, 36598, and 36599). The same part also cross-references to the Vesubio Filter and Europa Pro Filter ranges, making it a widely used component across the Fluidra commercial and semi-commercial filter portfolio. Always verify your model number before ordering.

Why Genuine Matters

As a genuine Fluidra OEM component, this nut is precision-matched to the Atlas filter’s discharge port thread specification. Using non-original hardware risks cross-threading, leaks, or damage to the filter body — especially on fibreglass-reinforced polyester tanks where replacement is costly. Genuine parts ensure long-term integrity of the discharge assembly.

Installation

The external discharge port nut works in conjunction with the internal discharge fitting (4404290105) to complete the sand drain assembly. It should be hand-tightened first, then torqued carefully to avoid overtightening on the polyester tank. Replacement is straightforward but is best carried out with the filter depressurised and drained. If in doubt, consult a qualified pool technician.
