What size and pressure capacity do you need??? US Plastics has teflon (chemfluor) tubing in at least 3 different varieties in sizes from 1/16" to 1/2" ID and pressure capacities from around 20 psi at 185 degrees to 175 psi at 185 degrees. Go to their site and look around, you will find what you need! Be prepared, though, you will have to spend some cash to get the highest quality teflon tubing. If you don't see what you need, call them! They are great to deal with and very helpful.
