Viton® ETP O-Rings also known as Viton® Extreme O-Rings provide significantly improved chemical resistance compared to standard Viton® A type fluoroelastomers. Viton® ETP is so chemically resistant it can be considered a cost-effective Kalrez® alternative for some applications with temperatures below 400°F. Viton® Extreme can also be considered as an alternative to other perfluoroelastomers like Chemraz®, Perlast®, Isolast®, Parofluor®, Markez®.

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.
