Works perfect.

Great product and value

It’s my 306 canister filter like a glove

Couplers work well for what they intend to do. Should last forever with their solid construction. Make sure you get the right diameter.

Used this to add an inline heater to my fluval 406 output line. Worked like a charm

A bit longer than the actual fluval size but still works. Good quality.

Put it to use as soon as it arrived.

Used this to split the Fluval hose that came with the 307 and to connect them to CO2 reactor which had 3/4” barbed fittings. Pushed them on the ends of the cut hoses as far as they’d go without a whole lot of effort. There’s a point where it’s visually obvious you’ve got them in far enough. Didn’t feel like I needed to glue or silicone them in place. Slid the other end over the barbs on the reactor and tightened down the barbed ends with hose clamps to reduce the risk of them getting pulled off. No leaks.

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