  • Made of 100% pure Viton, a high performance synthetic rubber
  • Excellent temperature resistance: -40ºF to 400ºF continuously; 600ºF periodically
  • Offers one of the widest ranges of fluid and chemical resistance of any commercial rubber
  • Excellent resistance to oils, fuels, lubricants, and most mineral acids
  • Also resistant to many aliphatic and aromatic hydrocarbons such as carbon tetrachloride, benzene, toluene, and xylene
  • Excellent resistance to environmental exposure such as sunlight and ozone
  • Available from stock in 60 and 75 Shore A durometers (Type A and Type B)
Notes

VITUBE's main attributes include exceptional chemical resistance at elevated temperatures. It has withstood continuous service temperatures of 600ºF for 48 hours and 500ºF for 1000 hours while maintaining its mechanical properties. However, care should be taken at these elevated temperatures. Tests should be performed to determine application suitability.

VITUBE possesses the high resiliency of an elastomer as well as the good mechanical properties of conventional synthetic rubbers. The heat and chemical resistance factors, however, usually go far beyond the range of other rubbers.

The 60A durometer compound is specially formulated for use in peristaltic pumps. All VITUBE formulations are produced with 100% DuPont Dow Viton fluoroelastomers (chemical name: fluorocarbon FKM) and are matte black in color. VITUBE contains no regrind material nor blends of other elastomers.

If accidental burning of VITUBE occurs, extreme caution should be taken due to Hydrogen Fluoride and other decomposition products. Avoid inhalation of vapors liberated at service temperatures above 392ºF.

If your application calls for harder VITUBE, 90A durometer is available.
