Pawfly 12 Pack Aquarium Heater Suction Cups Suckers with 0.95 Inch Clips Black Standard Heating Rod Holders Clamps for Fish Tanks (Not for Airline Tubing), 1.3 Inch

These are a great replacement for the suction cups on my aquarium heaters and other things that needs these. It's a bit big and its good quality from what I can tell.

Works great for my heater in my tank. It's holding my really long heavy tank heater very well.

This is a nice set of suction cups to keep on hand for use in the aquarium. Suction works great, too. Highly recommend.

Bought these to use for my gecko's vines, the size I got is a tad to big but sill useable.

The aquarium hooks were as advertised. The size chart accuracy is important ensure the aquarium accessories can fit and stabilized as required. A multiple sized suction hook box would be ideal.

Best suction cups I've found so far. These stick and stay. In fact they stay so well they are harder to take off than most. They are made of a high quality rubber that is thick and maintains the shape even after being stuck for a while. These are not like other suction cups that go flat after a few days and once removed can't be reused.

I have an aquarium heater that would no longer stick to glass because the suction cups had started to decay. These are a perfect replacement. The heater that I have shown in the picture is just under 1 inch diameter. These suction cups or for 0.95 in, and they fit perfectly. I also have some tubing, typically used for an under gravel filter, but I use them to route air hoses under the gravel. These tubes are 1.25” in diameter, and these suction cups do stretch fine and hold them secure.

Some are malformed and it affected the suction power. The ones that are not are great. Just fyi, you may get a dud or 2 in the box.
