These suction cups hold firmly on glass surfaces and keep the tubing in place without slipping. I’ve used them with my CO2Art IO diffuser and they work perfectly. Easy to install and reliable in daily use.
Oliver Ogden –
Great product for securing aquarium tubing. The suction cups stay in place even during water changes. No leaks or movement, which is a big relief for my setup.

Works well with 6mm tubing. A little bit harder to attach on smooth glass, but once secured, they stay put. Good value for the price.
