Ordered as V90327, this is an AS568-327 black Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 1.725 in (43.82 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.145 in (54.48 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Expect good resistance to chlorinated solvents, aggressive chemicals, and engine and transmission fluids. Viton® (FKM) is specified for excellent resistance to compression set and permeation, very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life.
It sees regular use in automotive fuel systems, semiconductor equipment, and high-temperature process equipment.
This item is sold individually under part number V90327. Unit weight is approximately 6.41 g and nominal inside diameter is listed as 1 3/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
