High-Vacuum Fluoroelastomer O-Rings

These O-rings are heat-treated, cleaned, and double-bagged in an ISO Class 5 (Fed. Std. Class 100) clean room for use in high-vacuum systems. Also known as baked O-rings, they are heated to 300° F to remove trapped air, gases, and other impurities that can escape and contaminate a vacuum system. Made of fluoroelastomer, these O-rings won’t degrade when exposed to chemicals such as benzene, butyl alcohol, and ethylene glycol. They have a round profile and are made to standard SAE AS568 sizes.
