Tygon® III

Smooth Bore Silicone Dairy Tubing

Tygon® III silicone dairy tubing from Saint-Gobain is designed to reduce the risk of particle build-up from butterfat, milkstones and milksoil. Preventing this build-up can significantly reduce the possibility of bacterial growth within milk transport lines, even during repeated use. The smooth bore of Tygon® III tubing helps prevent residue build-up, aiding in complete cleaning and sterilization.

Every foot of Tygon® III tubing has been embedded with a trademark blue stripe within the tubing walls. The embedded blue stripe is your assurance of receiving genuine Tygon® III tubing, the world’s finest raw milk tubing produced specifically for the dairy industry, designed to be long lasting, flexible, and easily installed.

Tygon® III tubing is manufactured in a climate-controlled environment. Highly flexible Tygon® III tubing is ozone- and UV light-resistant and can withstand continuous temperature extremes of -85˚F (-65˚C) to 320˚F (160˚C). Tygon® III tubing can also be used with full vacuum (29.9 inches of mercury) at up to 320˚F (160˚C) without tubing wall collapse.
