Broad Sand Filter Compatibility: Specifically molded to fit perfectly inside industry-standard sand filter tanks, including Aquamax, Aquaflo, Eartheco, Uni, Collins, and Quality systems.

Filter Media Containment: Acts as an internal guard that blocks sand, glass, or alternative media from bypassing the filtration loop and shooting back into your pool return jets.

Dual-Purpose Mesh Guard: Highly versatile 50mm design allows it to double as a reliable protection mesh cap for open hoses, intake pipes, and specialized filter fittings to keep debris out.

Aids Air Pressure Evacuation: Holds the internal automatic air bleeder tube securely in place at the top of the tank, allowing accumulated air pockets to escape without displacing the filter bed.

Durable Chemical-Proof Build: Injection-molded from heavy-duty, corrosion-proof polymer that sits submerged inside your filter tank for years without degrading or scaling under chemical treatment.
