Fluidra - Sand Filter Screw Neck Ring (20 Screws)

Fluidra – Sand Filter Screw Neck Ring (20 Screws)

This genuine Fluidra screw neck ring is the structural collar that mounts to the upper neck of the filter bowl, providing a secure and leak-free seating surface for the filter lid. Fastened by a total of 20 screws (12 lower, 8 upper), it includes a gasket to seal the joint between neck ring and bowl. It is an essential replacement part whenever the original ring is cracked, warped, or no longer holds a pressure-tight seal.

Compatibility

This neck ring is compatible with the Fluidra Europa Filter range (current 1½” arm models, 1 m filter bed, 2.5 kg/cm²) spanning tank diameters from Ø1050 mm to Ø2000 mm, including model numbers 20068–20072 and 21497–21510. It is also suitable for Fluidra Atlas and UVE sand filters fitted with a screw-type top closure. Always verify your filter model number before ordering.

Why genuine matters

Genuine Fluidra parts are manufactured to exact dimensional tolerances, ensuring the neck ring beds perfectly against the filter tank and lid. An ill-fitting aftermarket part can compromise the pressure seal and create unsafe operating conditions — particularly important on commercial filters rated to 2.5 kg/cm². Sourcing directly from the Fluidra catalogue guarantees the correct screw pattern and gasket specification.

Installation

The neck ring mounts to the top of the filter tank body using the 12 lower screws; the lid then fixes onto the ring via the 8 upper screws. The included gasket should be seated cleanly in its groove before tightening. Torque screws evenly in a star pattern to ensure an even seal. On large-diameter commercial filters, two people are recommended for safe handling of the lid assembly.
