Expect good resistance to many acids, engine and transmission fluids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) offers excellent resistance to compression set and permeation, outstanding high-temperature capability. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or hot water and steam are present.

Maintenance and OEM teams specify it across oil and gas, chemical processing, and aerospace.
