Fluidra - Volcano Filter Screw-In Lid with Seal and Nuts (Ø450–Ø900 mm)

Fluidra – Volcano Filter Screw-In Lid with Seal and Nuts (Ø450–Ø900 mm)

This is the genuine Fluidra replacement filter lid kit for the Volcano sand filter range, supplied complete with the lid seal and retaining nuts. It is designed to provide a secure, pressure-tight closure on the top of the filter tank, preventing leaks and maintaining correct system pressure during filtration and backwash cycles.

Compatibility

This lid kit is compatible with Fluidra Volcano sand filters fitted with a screw-in cover, covering tank diameters from Ø450 mm up to Ø900 mm (models 19774FB65, 19775FB65, 19776FB65, 19777FB65, and 19778FB65). Always cross-reference your filter’s model number and tank diameter before ordering to confirm fitment.

Why genuine matters

Using an original Fluidra part ensures the lid, seal, and nuts are dimensionally matched to your filter tank’s threads and sealing surfaces. An aftermarket lid with an incorrectly profiled seal can fail under operating pressure, leading to water loss or filter damage. The included seal and nuts mean you have everything needed for a complete, leak-free closure in a single kit.

Installation

The screw-in design allows the lid to be installed and removed without special tooling for routine maintenance such as sand changes or internal inspection. Ensure the old seal is fully removed and seating surfaces are clean before fitting the new seal, then hand-tighten the lid and secure the retaining nuts evenly to avoid distorting the seal. If you are unsure about working on a pressurised filtration system, professional installation is recommended.
