Sand Filter Lid 610mm — Replacement with O-Ring

Replacement lid for 610mm (4-bag) Aqua Max sand filters. The lid seals the top of the filter tank and gives you access to the sand bed for media changes, lateral inspections, and general maintenance. This lid comes complete with the O-ring seal — no need to source it separately.

When to Replace

Replace the lid if it’s cracked, warped from sun exposure, or the sealing surface is damaged and leaking even with a new O-ring. If you’re only getting a small leak around the lid, try replacing just the O-ring first before buying a full lid. The 610mm size fits Aqua Max 4-bag sand filters.
