AstralPool - Base Adapter 380/430 for Millennium Monobloc Filter Side Thread Ø380 - 4404300410

AstralPool – Base Adapter 380/430 for Millennium Monobloc Filter Side Thread Ø380

This is the genuine AstralPool replacement base adapter (position 13 in the official Fluidra exploded view) designed for the Millennium Monobloc Sand Filter with side-thread multiport valve, Ø380 mm (parent SKU 27804). It serves as the structural interface component that connects the Ø380 filter vessel to the monobloc base assembly, ensuring the filter, pump, and pipework sit correctly aligned and securely on the unit. Replacing a damaged or worn adapter restores the mechanical integrity of the entire monobloc filtration system.

Compatibility

This base adapter is engineered specifically for the AstralPool Millennium Monobloc Filter Side Thread Ø380 (SKU 27804). The 380/430 designation refers to the adapter’s role in bridging the Ø380 filter bowl to the wider base platform used across the Millennium monobloc range. Always verify your filter’s model number against the official Fluidra exploded view before ordering to ensure an exact fit.

Why Genuine Matters

As a load-bearing component in the monobloc assembly, dimensional precision is critical. Genuine AstralPool parts are manufactured to the exact tolerances required for the Millennium range, ensuring the filter body, pump, and base remain perfectly aligned under operating pressures of up to 2.5 kg/cm². Aftermarket substitutes may not replicate these tolerances, risking misalignment, leaks, or structural instability.

Installation

This adapter is a structural part of the monobloc base assembly and its replacement typically requires partial disassembly of the filter unit, including disconnecting pipework and the pump. Professional installation by a qualified pool technician is strongly recommended to ensure correct reassembly, proper sealing, and safe operation of the filtration system.
