At Continental we work with an extensive variety of materials including BUNA-N Nitrile (NBR), Chloroprene (®Neoprene), Fluorocarbon (®VITON), Fluorosilicone, HBNR, Polyacrylic, Silicone, TFE/P (®AFLAS), FFKM, Ethylene Acrylic Elastomer (®Vamac) and Ethylene-Propylene. All have excellent physical properties and compounds are available which meet Government, Automotive, F.D.A., UL, and NSF industrial and commercial specifications.Continental will work with your company to select the appropriate material for your application, and can develop custom compounds to meet your specification.


Buna-N Nitrile (NBR)

The standard for most general sealing applications; petroleum base lubricants, hydraulic oils, gasoline, fuels, alcohol, L.P. gases, water and many other media. High saturated (hydrogenated) Nitrile materials also resist ozone and temperatures up to 350°F. NSF materials also available. Temperature Range: -65° to +275°F

® Neoprene (Chloroprene)

Recommended for refrigeration freon gases, carbon dioxide, chlorine, ozone, sunlight exposure and for use as drive belts. F.D.A approved compounds are available for food and beverages. Odorless, tasteless and non-toxic. Temperature Range: -65° to +275°F


For hot water, steam, acids, alcohols, alkalis, ketones, phosphate esters, brake fluids, drive belts, exposure to oxygen, ozone and weathering. NSF materials also available. Temperature Range: -67° to +400°F

® Viton (Fluorocarbon)

High temperature toughness, stability, and compatibility with a wide range of fluid and chemical types including acids, oils, fuels, solvents and gases. Temperature Range: -40° to +500° F


Compatible with a variety of fluids, air, oxygen, ozone and other media for extreme use of low and high temperature applications.Temperature Range: -100° to +500°F


Recommended where extreme temperature properties are required. For petroleum oils, fuels and lubricants; synthetic ester and diester lubricants.Temperature Range: -100° to +400°F

In Addition

Continental’s standard O-Rings are also available in all rubber elastomers, synthetic or natural, including:Butyl, Polyurethane, SBR, Polyacrylate, ®Hypalon, ®Hydrin, Perfluoroelastomers, and Conductive Materials.
