Low-Outgassing Chemical-Resistant Viton® Fluoroelastomer O-Rings
Tested to meet ASTM E595, a standard used by NASA, these O-rings give off almost no volatile emissions that could damage sensitive electronics, even in a vacuum. They’re made of Viton® fluoroelastomer, so they also resist a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol. A round profile is good for sealing both moving and stationary parts. All are sized to the SAE standard AS568.
