Where can I find some co2 safe line

[Delsfishes]

I know all the lines are pretty much the same and will work ,but I had better luck with the co2 safe line as they are more flexible and last longer with the co2 any idea where I can pick some up locally?

Thx

Try the planted aquarium. I think they have something that works.
