Ordered as VB75020, this is an AS568-020 brown Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 0.864 in (21.95 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.004 in (25.5 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.
The compound resists many acids, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) offers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or ketones and esters are present.
Maintenance and OEM teams specify it across chemical processing, oil and gas, and semiconductor equipment.
Order part number VB75020, sold individually. Unit weight is approximately 0.3911 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
