VB75212 is an AS568-212 brown Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 0.859 in (21.82 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.137 in (28.88 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Viton® (FKM) is widely chosen for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. It resists petroleum oils and fuels, aromatic hydrocarbons, and many acids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where ketones and esters or low-molecular-weight organic acids are present.
You will find this material specified across chemical processing, semiconductor equipment, and aerospace.
Order part number VB75212, sold individually. Unit weight is approximately 1.6024 g. Check the compound against your process media, pressure and temperature before committing to a design.
