🔩 Fluval Suction Cups with Clips: (4) 4x12 mm and (8) 4x14 mm for 03, 04, and 05 Series Review

At the time of writing this review, some of these have been used for 8 months! By far the strongest and best quality I've ever used. Will definitely order again!

They suck, but it's good, they suck and stay on the glass. I have some outside my tanks and some underwater. NO problems, no slips or falls. They stay where they are and I live that A++

Works well, I've used it for both inlet and outlet. The larger clamps only fit the smaller tube and curved outlet base. Suction cups work well if you clean the glass before attaching.

Still looking for the holy grail of suction cups. They work well but still separate quite often. Granted, they're designed for a turtle tank, so not necessarily "in". Pretty good though for my Fluval 406 hoses.

I also used them to hold the outlet tube on my Fluval 406. They should have come with the filter. Perfect size for the Fluval Filter Tube (Black Finned Tube) Quite expensive but they work.

Eheim heaters are guaranteed not to fry your fish. But their suction cups dry up after 6 months of use. Luckily these amazing suction cups (only 4) from Fluval are perfect for the Eheim heater mount which only needs 2. They last a lifetime, Fluval engineers are the best.

I don't know why people are complaining about these suction cups. I have a Fluval 305 filter and the suction cups holding the intake manifold to the glass were rock hard. Bought these replacement parts and they fit and work perfectly. Now I have two extra in case they get hard again. Thanks very much!

Expensive but worth it. They stick and you have to work hard to remove them. LOL I'd rather have to keep putting them back in place afterwards. My only complaint is that it would have been nice if they came a size larger with clips/clips. However, I have had other clamps/clamps that fit these suction cups. Pretty versatile.

I actually use them to keep the channels in place. I bought regular pipe clamps and suction cups and they stopped working after a few weeks because of the cheap plastic. They are supposed to be for the inlet/flush of a canister filter or heaters (they work well with those too) but I bought an extra kit just for ducting. So my larger cichlids can no longer knock over air ducts!
