Which tubing material is affordable, flexible, widely available, and suited for transporting very pure acids ("puriss." products) in their most concentrated form without contaminating them?

PTFE seems compatible with most if not all of them, but I don't think it's very flexible, and I'm not sure whether PTFE hoses would be affordable (nor where I could buy some).
