CHOOSING A TUBING MATERIAL

The best way to select a tube is to first decide which materials are chemically suitable, and then choose the one which best meets the physical demands of the application.

Always make an immersion test before choosing a tube material for critical applications. Immerse a short length of the tubing (ask for a tubing sample card from Watson-Marlow) in a closed container of the fluid for 48 hours, and then examine it for signs of attack, swelling, embrittlement or other deterioration.
