Fluval Rubber Adapter for Ribbed Hosing, 304, 305, 404, 405 (2 Pieces)

These are nice to have on hand for changing stem lengths and emergency repairs. The only thing I dont like is...the price! Seems everything Fluval makes is gold plated...very spendy!

Do not buy Fluval Filters. I have two of them representing $600 in purchases. Both filters leak and I have found other reviews warning of the same problem. The leak is usually through the Primer Assembly and replacing the part will NOT solve the problem. I wish I could retract my previous review, however I will warn anyone who reads this the filter units will eventually leak!

Just like all Hagen products they just work. The parts fit they go together easily and no leaks what more could you want. good product buy it.

Fits fluval 406 tubing perfectly.

very good product

I used these to install an in-line co2 reactor. I didnt realize I needed them at first, so I was frustrated that I had to buy something else. Once they arrived, they were easy to install and leak proof a week and going. I can confirm these work for the hose that comes with the newer 307 filters. I used one for the co2 reactor and one on the filter valve itself. They fit perfectly for both. Edit: two years and a move across town later and these have still never leaked.

Put it to use as soon as it arrived.

If youre wanting to connect your Fluval 406 to a UV sterilizer, this is what you need for a leak proof installation

Bought this item twice. Love it! Fits a variety of hoses and fittings with no leaks. WHY did it go from $ 8.91 in price to $12.49. in a couple of months? Guess I got as many as I will need!

Works perfect.
