An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The compound resists chlorinated solvents, many acids, and aromatic hydrocarbons. Viton® (FKM) is widely chosen for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in ketones and esters or low-molecular-weight organic acids.
Common environments for this compound include high-temperature process equipment, semiconductor equipment, and oil and gas.
Order part number VITON75049, sold individually. Unit weight is approximately 1.8606 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
