Thin but flexible
Reviewed in Canada on April 4, 2019
It’s thinner than my other airline tubing, but it’s quite flexible and still fits in all of my accessories (filter, air pump, air stones, 4-way valve, check valve).
I had to use a bit more force to fit it into some of the accessories (compared to when using my other tubing), but after that there was no problem. To me it’s not that big of deal considering how cheap the price was.
In the pictures you can see this item is the one that has a smaller diameter.
