Viton 75-350-Black-Pk2

The SB-V70350-2 is an AS568-350 black Viton® (FKM) 70 Shore A O-Ring with an inside diameter of 4.6 in (116.84 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.02 in (127.51 mm). 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 0.210CSX4.600"IDX5.020"OD.

Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Expect good resistance to petroleum oils and fuels, chlorinated solvents, and many acids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving low-molecular-weight organic acids or ketones and esters call for a different compound.

Typical settings include high-temperature process equipment, chemical processing, and semiconductor equipment.

Order part number SB-V70350-2, sold by the bag. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
