The VB90278 is an AS568-278 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 11.984 in (304.39 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 12.262 in (311.45 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
As a material, Viton® (FKM) offers excellent resistance to compression set and permeation, outstanding high-temperature capability. It resists petroleum oils and fuels, aromatic hydrocarbons, and many acids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or amines will shorten service life.
It sees regular use in oil and gas, automotive fuel systems, and semiconductor equipment.
Stocked as VB90278 and sold individually. Unit weight is approximately 21.1202 g. Check the compound against your process media, pressure and temperature before committing to a design.
