### ⭐⭐⭐⭐⭐ Problem....Solved!
*by A***H on March 29, 2019*

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!
