-322 BROWN FKM 90D O-RING

APG stocks the VB90322, an AS568-322 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 1.225 in (31.12 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.645 in (41.78 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists many acids, aggressive chemicals, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is specified for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. 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 amines or low-molecular-weight organic acids.

You will find this material specified across semiconductor equipment, aerospace, and oil and gas.
