Silicone is perhaps the ideal hose for the environmentally conscious brewer because it is non toxic at any temperature up to 500 ˚F. It can be boiled to be completely sterilized, eliminating the need to frequently replace vinyl tubing. It can be stretched to fit if needed, and will spring back to shape. This tubing will get stained by normal brewing over time but will retain its translucent appearance so you san see liquid flowing through. This tubing is thick walled so it will not collapse during hot transfers. Not suited for high pressure applications- it will burst if pressure exceeds 20 psi.
A rubber-like thermoset material, silicone tubing and hose is extremely pliable and elastic, and it is not altered by the effects of weather. It generally exhibits inertness toward U.V., radiation, and ozone making.
