It resists petroleum oils and fuels, many acids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) offers very low compression set at elevated temperature, excellent resistance to compression set and permeation. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where amines or ketones and esters are present.
It sees regular use in chemical processing, automotive fuel systems, and semiconductor equipment.

Review your operating media and conditions against this specification before installation.
