Fluidra - Millenium Sand Filter Gasket Set 3–5.5 HP (Top Outlet) - 4405010527

Fluidra – Millenium Sand Filter Gasket Set 3–5.5 HP (Top Outlet)

This is the genuine Fluidra replacement gasket set designed for the Millenium Sand Filter (Top Outlet) range, covering the 3 HP to 5.5 HP models. The kit supplies all the seals needed to restore a watertight, leak-free filter assembly during routine servicing or after a pressure fault. Using official Fluidra gaskets ensures correct material grade, dimensional accuracy, and compliance with the filter’s 2 kg/cm² maximum working pressure rating.

Compatibility

This gasket set is compatible with Fluidra AstralPool Millenium Sand Filters fitted with a top-outlet multiport valve, specifically the 3 HP to 5.5 HP model variants (refer to your filter’s model number and technical documentation to confirm the correct HP range before ordering). It is not intended for Millenium side-outlet or lower HP configurations.

Why Genuine Matters

Genuine Fluidra spare parts are manufactured to the same tolerances as the original components, ensuring a reliable seal under the thermal cycling and chemical exposure typical of pool water environments. Aftermarket gaskets may differ in compound hardness or profile, risking premature failure, water loss, or pressure drops that reduce filtration performance.

Installation

Before fitting, relieve all system pressure and drain the filter body. Clean all mating surfaces thoroughly to remove any old gasket material or debris, then seat the new gaskets carefully without lubricants unless specified by the Fluidra service documentation. A qualified pool technician should perform or supervise the service to ensure safe recommissioning.
