Review on Fluval Motor Seal Ring Gasket by Holly Rivera

If you have a Fluval canister filter, you should order one of these; So you have everything ready for the day you need it. The one that came with my filter lasted about 10 months before it started leaking. The replacement was easy and the leak stopped. I've since ordered a second one and have it ready just in case. I just wipe mine with a damp paper towel to avoid buildup. The one that came with my filter lasted about 10 months before it started leaking. It's always nice to see how much garbage one of these rings gets when it's installed. Do not use cleaning chemicals on the o-ring, they will damage it by melting or hardening the surface, resulting in premature failure. I've since ordered a second one and keep it handy just in case.
