Tygon® F-4040-A tubing has been specially-formulated for use in petroleum (and similar) applications where other Tygon blends cannot be used successfully. In addition to being suitable for hydrocarbon-based applications, this material can also be used successfully with low-concentration acidic solutions as well as mineral salt solutions. The material offers some of the lowest gas permeability rates for atmospheric gases of all the Tygon blends, making it ideal for use in those applications where sensitivity to gas permeation is high or where vacuum may be applied. Yellow-tinted, the material offers some degree of translucency, however, it is not as transparent as many other Tygon blends. Tygon F-4040-A tubing has a limited shelf life and should be purchased close to the usage date.

Advantages:

• formulated to transport pertoleums, hydrocarbons and distillates
• ideal for gasoline, kerosene, heating oils, cutting liquids and coolants based on glycol
• very low gas permeability
• high dielectric constant

  * Gas permeability: (Volume of Gas [cm³] x wall thickness [mm]/Area of tubing ID [cm²] x time [sec] x pressure drop across wall [cmHG]) x 10^-10
