High-Vacuum Chemical-Resistant Viton® Fluoroelastomer O-Rings
Heat treated, cleaned, and double-bagged in an ISO Class 5 clean room, these O-rings come ready 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.
