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

I used this on a humidifier to hook to the Fluval hoses to pump humid air into my Ball Pythons terrarium.

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

Works as expected

Works as described

After reading reviews on this item i was sure i would receive the black ones...........But no such luck. They were white. So i Sent them back. The photo on here needs to be updated .

Put it to use as soon as it arrived.

Perfect for my tank

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

As someone else said, if its not clear where/what these parts fit, heres a photo of them installed on a Fluval 305, connecting the tubing to the intake and outflow components in the aquarium. These light-grey pieces were a perfect replacement for the old black couplers (one of which Im holding in the photo, for comparison).
