Fluval Suction Cups, (4) 4x12 mm and clips, (8) 4x14 mm (03, 04 and 05 Series)

These work great and stay on the aquarium glass. I wanted them to try to make it harder for our dojo loaches from being able to separate the filter tubing from these by using two. The dojo loaches have won that battle. But overall it's good. Our dojo must be practicing a lot of karate because so far nothings worked.

The old suction cups of mine were full of pink algae. this is perfect for my application!! Thank u

I purchased this item a while ago but I finally got around to installing them a few days ago. These suction cups seem to work pretty good but only time will tell if they're worth the money. I hope they don't get all hard like the cheap kind. I suppose I'll post an update in about a year or a little less and let you guys know how they're doing. I like everything about them except for the clips which could be of a slightly greater diameter but whatever.

I don't know why people are complaining about these suction cups. I have a Fluval 305 filter and the suction cups that hold the intake stem on to the glass were hard as a rock. Bought these replacements and they fit and function perfectly. Now I have two extra ones just in case they harden again. Thanks!

Pretty reliable suction cups. Very well made. They attach perfectly to glass and acrylic surfaces. I use them on the back of my tank to help route cables and in my sump to help route my ato water hose. Never had an issue with them falling off, etc. Recommend to anyone.

The Fluval Suction Cups are good for some things, but not quite what I was looking for. I am sure I will be able to use them in a different application.What I was actually looking for were suction cups capable of carrying American Flags on the trunk of my Corvette.Thank you

Been using a few of these for 8 months at the time of this review! So far the strongest and best quality I ever used. Will definitely order again!

I actually use these to hold air lines in place. I have bought the regular air line clips and suction cups and they are stop working a few weeks due to cheap plastic. These are supposed to be for canister filter intake/blows or heaters (they work excellent on those too) but I bought an extra set just for air lines. This way my larger cichlids can't knock the air lines around anymore!

Bonne qualité , bon prix , service rapide .
