In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. This item is further identified as 0.275CSX7.475"IDX8.025"OD.

Viton® (FKM) is specified here for excellent resistance to compression set and permeation, very low compression set at elevated temperature. This material stands up to many acids, engine and transmission fluids, and chlorinated solvents. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or low-molecular-weight organic acids call for a different compound.

You will find this material specified across high-temperature process equipment, chemical processing, and automotive fuel systems.

SB-V70443-2 ships by the bag. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
