The information on this page is to the best of our knowledge accurate and reliable. However, Marco Rubber makes no warranty, expressed or implied, that parts manufactured from this material will perform satisfactorily in the customer's application. It's the customer's responsibility to evaluate parts prior to use.
The temperature ranges presented on this page are approximations for dry air service only and should not be used to determine design specifications or end-use temperature limits. Actual temperature range of a compound in an end-use application is highly dependent on part type, hardware configuration, applied forces, chemical media, pressure and thermal cycling effects, and other factors. The most practical way of determining an end-use temperature range is testing in the actual application conditions. Consult a Marco Engineer for more details.

Fluoroelastomers are referred to generically as FKM polymers per the nomenclature noted in ASTM D1418. In the SAE J200 ASTM D2000 classification system for rubber materials Fluoroelastomers are documented as a “HK”.
The key advantage of Viton® rubber is its dependability in a range of harsh conditions. Viton® rubber can withstand exposure to almost any substance, including aggressive chemicals, oils, fuels, acids, gasses, and solvents. It is also known for its ability to resist extreme heat-with a wide temperature operating range of -15°F to 430°F. (Lower temperature compounds are also available.)
