Viton® (FKM) is known for outstanding high-temperature capability, excellent resistance to compression set and permeation. 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 ketones and esters or amines are present.

The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. You will find this material specified across high-temperature process equipment, semiconductor equipment, and aerospace.
