Viton ORings - Fluorocarbon Elastomers

 

Fluoroelastomers, Fluorocarbon O-Rings or commonly called Viton O-Rings can exhibit exceptional resistance to heat, aging, weather, ozone, oxygen, and sunlight, as well as to a broad range of fuels, solvents, and chemicals. AMS 7276 O-Rings, Parker O-Rings, GLT Type Viton O-Rings are some of the many varieties available at Anchor Rubber. We carry custom, standard and metric viton o-ring sizes. Viton hydraulic seals and viton gaskets are also sold and custom manufactured here. See the below chart for characteristics and data sheets for some of the many fluorocarbon compounds available.
