Tygon tubing

Tygon is a brand name for a family of flexible polymer tubing consisting of a variety of materials to be used "across a range of specialized fluid transfer requirements". The specific composition of each type is a trade secret. Some variants have multiple layers of different materials. Tygon is a registered trademark of Saint-Gobain Corporation. It is an invented word, owned and used by Saint-Gobain and originated in the late 1930s. Tygon products are produced in three countries, but sold throughout the world. Tygon tubing is used in many markets, including food and beverage, chemical processing, industrial, laboratory, medical, pharmaceutical, and semiconductor processing. There are many formulations of clear, flexible, Tygon tubing. The chemical resistance and physical properties vary among the different formulations, but the tubing generally is intended to be "so resistant to chemical attack that it will handle practically any chemical", whether liquid, gas, or slurry. Users should be cautious to match the characteristics of the tubing being considered with their own specific requirements.

Tygon B-44-3, Tygon B-44-4X, Tygon B-44-4X I.B., and Tygon Silver (antimicrobial) were widely used in the food and beverage industry, in particular in: beverage dispensing, dairy processing, soft-serve dispensing, vitamin and flavor concentrate systems, cosmetic production, and water purification systems. These formulations each meet U.S. Food and Drug Administration 3-A and NSF International 51 criteria but they do not comply with European Directives (European Directive 2002/72/EC of 6 August 2002 relating to plastic materials and articles intended to come into contact with foodstuffs as modified in particular by Directive 2007/19/EC of 2 April 2007).

Several formulations of Tygon are USP class VI approved and can be used in either surgical procedures or pharmaceutical processing.
