Looking for rubber tubing that can take the heat? Silicone is a synthetic rubber that's more resilient than natural rubber, making it a popular choice for vacuum pumps. Tubing won't impart taste or odors and maintains its flexibility over time. Use with water, air, and food and beverage. Tubing is made from FDA-compliant resins. Material meets ASTM D2000. Tubing can be sterilized with steam (autoclaving) and radiation.
