Teflon hose offers superior chemical resistance and high temperature qualities, making it ideal for the harshest conditions. A Teflon hose generally consists of two parts. The first part is the base of the hose, which is typically a fabric type material such as fiberglass. The Teflon is then coated onto the hose, sealing the fabric and creating the highly chemical resistant lining for the hose. Typically wire reinforcement is used as the “backbone” of the hose, which also reduces kinking when the hose is flexed. Therefore a Teflon flexible hose behaves like a fabric hose while offering excellent chemical resistance.
Teflon, also known scientifically by its chemical make up as Polytetraflouoroethylene, is made up of Carbon and Fluorine atoms, categorizing it as Fluorocarbon. The strength of these Carbon-Fluorine bonds is what lends Teflon its excellent chemical resistanct and hydrophobic properties. Hydrophobic materials are unable to be “wetted” by anything containing water.
Though less affordable than other options, this particular material offers an outstanding resistance to a huge variety of chemicals. This trait doesn’t just make a Teflon flexible hose highly durable, it also makes it excellent for use in applications where the purity of the fumes passing through it must be maintained. Due to the material’s non-reactive molecular structure, a Teflon hose can be used for extremely precise fume transfer such as in pharmaceutical applications or even more abrasive situations like pollution control. The malleability of the material also allows for a number of available Teflon flexible hose sizes, which paired with its wide range of use within different temperatures, makes this a highly efficient, durable, and functional product.
The chemicals that a Teflon hose is resistant to includes several caustic acids that would destroy almost any other hose quickly. Teflon is so chemically non-reactive, it is used to store acids such as hydrofluoric acid and fluoroantimonic acid—a “superacid”, defined as an acid with an acidity that is greater than 100% of pure sulfuric acid. Of course, specific chemical resistance requirements should always be verified before choosing a Teflon flexible Hose to ensure compatibility. We offer a convenient chemical resistance chart that includes many commonly encountered chemicals, with specific ratings (A to D) so it is easy to pick out the appropriate hose for specific applications. This form can easily be viewed as a PDF from the “Hose Downloads” link, found on at the bottom of any webpage.
