I want tubing that isn’t very permeable to gases. What can I use?

Your best option when choosing tubing, keeping in mind its permeability to gases, is metal tubing, such as stainless steel or titanium. However, these are often not very convenient to use in places where you would be most concerned about gases permeating the tubing walls. Often, polymer tubing is the tubing of choice for flexibility and ease of cutting purposes. But which is least permeable to gases? For the best performance, PEEK tubing should be your option of choice, as its gas permeability is virtually undetectable. Most fluoropolymer tubing, including Tefzel and Teflon tubing, is highly gas permeable and should not typically be used where gas permeation may be detrimental.
