I'm not sure if there are different models of the FX 4 but the O-ring for the FX 5 does not fit the FX 4 like some folks claims it does. I purchased one and was disappointed.

Had a leaky FX5 - a model that fluval seems to have tries hard to hide these days while fx4 and fx6 are still widely talked about.This o-ring solved my issue on the first go. Not even a single drop. Perfect.Thanks for having this available!

Does the job it's intended to and I like that the fx5 seal rings can be used with the fx4 canister filters. This is MUCH CHEAPER than ordering from fluval directly so that's a plus for me.

Its designed for the filter and fits perfect. My FX5 filter was still running great after three years of continuous use but I decided to replace all the seals to be on the safe side.

I bought this for my fx5 as and back up replacement. Seems to be legit so I have no doubt that it would work great.
