Netafim™ O-Ring Cover for Manual Disc Filter - For 3/4in Disc Filter Model 25A45

Replacement O-Ring Cover for 3/4in Disc Filter Model 25A45

A cracked or worn cover on a disc filter housing lets unfiltered water bypass the filter disc stack, defeating the purpose of the filter in the first place. Netafim's O-ring cover is a direct replacement part sized specifically for the 3/4in Model 25A45 manual disc filter, restoring a proper seal without replacing the entire filter body.

Keeping a spare cover on hand means a worn seal is a quick swap instead of downtime while a full replacement filter is sourced.

• Restores housing seal — stops unfiltered water from bypassing the disc stack through a worn or cracked cover.

Frequently Asked Questions

What filter does this cover fit

It's a direct-fit replacement for the 3/4in Model 25A45 manual disc filter housing. Confirm your filter model before ordering, since disc filter covers are sized to a specific housing.

How do I know if I need to replace this cover

Signs include visible cracking, a housing that no longer seals tightly, or unfiltered debris passing through despite a clean disc stack. Any of these point to a worn seal rather than a problem with the filter discs themselves.

How do I install the replacement cover

Remove the old cover from the filter housing, clean the sealing surface of any debris, and seat the new O-ring cover in its place. Check that it seals fully before returning the filter to service.

Do I need to replace the whole filter if only the cover is worn

No, this cover is sold specifically so growers can replace just the worn or cracked part rather than the entire filter body. It's a lower-cost fix than sourcing a full replacement filter.
