In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The compound resists petroleum oils and fuels, engine and transmission fluids, and many acids. Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).
This item meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Typical settings include chemical processing, high-temperature process equipment, and semiconductor equipment.
