O-Rings

Teflon o-rings are known for high heat resistance, high resistance to chemical agents and solvents, anti-adhesiveness, dielectric properties, low friction coefficient, and non-toxicity. Polytetrafluoroethylene (PTFE) is a high molecular weight polymer, one of the most versatile plastic materials known and useful for a large range of products for applications excluded from other materials.

AFLAS® o-rings are highly resistant to a wide range of chemicals, such as acid, base, and steam. Frequently used for Downhole, General Steam, Marine Engines, Mechanical Seals.Performs well in Petroleum fluids, Brake fluids, Bases, Phosphate esters, Amines, Engine oils, Steam and hot water, Pulp and paper liquids.Does not perform well in Aromatic fuels, Ketones, Chlorinated hydrocarbons.

Generally, EPDM o-rings are known to possess excellent resistance to ozone, sunlight, and weathering, and has very good flexibility at low temperature, good chemical resistance (many dilute acids and alkalis as well as polar solvents), and good electrical insulation property. EPDM o-rings are useful for a number of industries from automobile assembly to water purification systems.Performs well in Alcohols, Automotive brake fluid, Ketones, Dilute acids and alkalis, Silicone oils and greases, Steam up to 204.4ºC (400ºF), Water, Phosphate ester based hydraulic fluids, Ozone, aging, and weathering.Does not perform well in Aliphatic and aromatic hydrocarbons, Di-ester based lubricants, Halogenated solvents, Petroleum based oils and greases.

Fluorosilicone (FVMQ) is like side chains of silicone rubber, bonding trifluoropropyl, methyl and vinyl. Fluorosilicone o-rings have low abrasion resistance and are preferred for use in static environments. fluorosilicone o-rings are most commonly utilized in aerospace applications and are becoming more widely accepted for general purpose use.Performs well in Fuels, Aromatic mineral oils, Benzene, Toluene, Ozone and weather.Does not perform well in Brake fluids, Ketones, Hydrazine.

Hydrogenated Nitrile (HNBR) o-rings, also known as Highly Saturated Nitrile (HSN) results in the superior heat, ozone, chemical resistance and mechanical characteristics over standard Nitrile. HNBR o-rings are usually peroxide-cured but can also be sulfur-cured to improve flexible properties in dynamic systems. However, sulfur-curing will reduce the heat resistance and cause an inferior compression set.Performs well in Petroleum based oils and fuels, Aliphatic hydrocarbons, Vegetable oils, Silicone oils and greases, Ethylene glycol, Dilute acids, bases, and salt solutions to moderate temperatures, Water and steam to 150ºC (300ºF).Does not perform well in Chlorinated hydrocarbons, Ketones, Ethers, Esters, Strong acids.
