Exactly what we needed when ours got rain rot and dried out I was so happy it was exactly as described.

While these or any O-Rings don’t really need to do much, these fit our situation and seem to be doing the job they were designed to do.

My AP system was installed in 2008 making it an older version. These square o-rings fit perfectly. The newer version (round) o-rings are 1/4” too large and don’t seal properly. Buy these.

They were the only seller to give info on the flat o-ring option. My water filter housings are going on 30 + years old so, finding some one who carried them saved me a ton of cash. To replace the housings it would have cost me at least $260.00 for the parts. If I had to hire a plumber, who knows.Thanks!!, Jim

After we changed the whole house water filter, the gasket was leaking. This O-ring fit perfectly and fixed the water filter housing leak.

Bought to replace O-ring for Pentair Pentek RFC-BB Big Blue Carbon Water Filter (10-Inch). Didn't fit into housing due to shape and size. Expensive rubber bands.

Don't use Vaseline on the "O" rings. It makes them swell so next time you change the filter, the O ring will be too large. Use Silicone "O" ring grease instead.
