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

Fluval adaptor, fluval quality, arrived on time.

I used these to install an in-line co2 reactor. I didn't 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.

Works great and easy to use.

Impeccable et fonctionne parfaitement pour la pompe fluval 307 pour y raccorder un chauffage externe ou autre car il est noté sur le produit pour fluval 306 .👌

Perfectas para un fluval 407, las utilice para conectar el reactor externo de CO2, realice una adaptación pero todo quedó muy bien....
