-350 BLACK FKM 90D O-RING

APG stocks the V90350, an AS568-350 black Viton® (FKM) 90 Shore A O-Ring supplied 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). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists chlorinated solvents, aggressive chemicals, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is specified for excellent resistance to compression set and permeation, very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in ketones and esters or hot water and steam.

It sees regular use in aerospace, semiconductor equipment, and high-temperature process equipment.
