As a material, Viton® (FKM) is widely chosen for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The compound resists aromatic hydrocarbons, many acids, and chlorinated solvents. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or amines are present.
Maintenance and OEM teams specify it across aerospace, semiconductor equipment, and oil and gas.
This item is sold individually under part number VB75209. Unit weight is approximately 1.3135 g. Check the compound against your process media, pressure and temperature before committing to a design.
