Low-Outgassing Chemical-Resistant Soft 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 softer than standard Viton®, so they better conform to irregular surfaces. And thanks to their material, they resist a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol. Their round profile is good for sealing both moving and stationary parts. All are sized to the SAE standard AS568.
