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

Works well, needed these to hook in a inline co2 difusser to my fluval 406

OE hose adapters fit my fluval 207 perfect

worked as advertised. I just wish I could get them in black.

Received the original rubber adaptor. I connected to lily Pipe. Perfectly fit. No leak.

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.

Great product and value

Worked as it should.

Excelent

fare price works like it is suppose to.

Work fine for what they are made to do. My only complaint is how long these should last, I feel like they should go longer than 18 months. I get that an aquarium is probably a harsh environment for rubber, but these arent moving parts.
