Industrial use
There are several formulations of Tygon that are used in industrial applications.
Tygon Fuel and Lubricant Tubing F-4040-A is translucent yellow for positive identification and flow monitoring. It is used in small engine fuel lines, recreational vehicles, and lubrication lines.
Tygon LP1000 is a low permeation California Air Resources Board (CARB) rated small engine fuel line and Tygon LP100 is a low permeation United States Environmental Protection Agency‎ approved material also used in small engines.
Tygon R-3400 UV Resistant Tubing is black in color and opaque. It remains flexible in ultraviolet environments and is often used for electrical insulation lines, ink and adhesive dispensing, and fertilizer and pesticide dispensing. Because it is resistant to UV light, ozone and weathering, it is commonly used in outdoor applications.

I don't know how UV resistant the green is. I guess you could leave a small piece outside and find out.

Don't remember the name of the product or where Chris found it, but the intended use of the fuel line used by Quincy Welding was beer dispensing.
