Replacement A20063 A20064 Orings for Fluval 304, 305, 306, 307, 404, 405, 406, 407 Canister Filter Motor Head Lid Seal Ring (2 Pack)

Capital rings are great I have a fluvall 407 and a 107 and purchase the o-rings for both The nice thing is is you get two o-rings per package so even in the event that the factory one fails you still have a second backup they fit like a charm just remember to put some o-ring grease that's not petroleum based look for food safe Billy skin actually makes a food safe and food contact o-ring lubricant comes in a tube and pretty well priced these will be my go-to from here on out I've had to change one o-ring on each pump and I still have an extra one left over at their price it's a steal it's definitely worth having o-rings and replacing them every once in awhile than having a flooded house and dead creatures

I used some dielectric food safe grease to lube up the O-ring and installed it on my Fluval filter, no more leaks! Its been working for the past 8 months so I'd say its a durable and quality product.

Fast shipping. Item as described

Product worked perfectly. Easy to install. No leaks!

Barato y se ajusta bien. Debería venir lubricado.

Basically, it stopped me from throwing away my recently bought 307 canister filter into the bin. The gasket that came with the filter is absolute trash, so if you want a system working as it should you must get this o-ring instead.

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.

These work great in both my Fluval 405 and 407 canister filters.
