Great replacement
These O-rings are a great fit and replacement part for the Fluval 307 and 407 cannister filters. Whenever I do filter maintenance every 3 months I change out the O-rings. Filter has never leaked or given me issues on fitment.

Works great
Original Fluval O-ring broke in 2014 and leaked all over the floor. It created a syphon and dumped approximately 30 gallons of water from my turtle's tank onto the floor. Since then, I periodically change the o-ring with these (about once every 2 years) and have not had a problem. Works as advertised.

Fits fluval perfectly
Works great, my filter had constant purges due to a leaking o ring on the suction side. Fits great, no more air purges.
