O-Rings - Global O-Ring and Seal

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.

Nitrile rubber (NBR) o-rings, also known as Buna-N, are one of the most commonly used sealing elastomers due to resistance to petroleum-based fuels and lubricants and its relatively low price. Standard Nitrile o-rings are usually sulfur-cured. Sulfur-cured compounds offer better low-temperature properties but are more prone to hardening with high temperatures. Performs well in Petroleum-based oils and fuels, Aliphatic hydrocarbons, Vegetable oils, Silicone oils and greases, Ethylene glycol, Dilute acids.Does not perform well in Aromatic hydrocarbons, Automotive brake fluid, Chlorinated hydrocarbons, Ketones, Ethers, Esters, Phosphate ester hydraulic fluids, Strong acids, Ozone, weathering, and sunlight.

Silicone o-rings have excellent heat, ozone and corona resistance and have good dielectric stability and resistance to many oils, chemicals and solvents. Silicone o-rings maintain the best flexible property at low temperatures but have low tensile strength and low wear and tear resistance. Performs well in Engine and transmission oil (mineral oils), Diluted salt solution, Moderate water, Dry heat, Ozone and weather resistance.Does not perform well in Concentrated acids and alkalis, Steam over 120ºC (248ºF), Petroleum oils and fuels, Ketones.

FKM is a well-known high-performance rubber that has excellent resistance to high temperature, ozone, weather, oxygen, mineral oil, fuels, hydraulic fluids, aromatics and many organic solvents and chemicals. Outstanding resistance to heat, oxidation, weathering, ozone; Outstanding resistance to a broad variety of fluids, including: aliphatic and aromatic hydrocarbons, halogenated fluids, strong acids; Outstanding resistance to compression set, providing sealing performance and longevity unmatched by any non-fluorinated elastomer.Performs well in Petroleum products, Fuel or blend with methanol or ethanol, Diesel or blend with biodiesel, Mineral oil and grease, Silicone oil and grease, High vacuum, Ozone, weather, and very high temperature air, Strong acid.Does not perform well in Ketones, Low molecular weight organic acids, Superheat steam, Low molecular weight esters and ethers, Phosphate ester based hydraulic fluids.

Neoprene is a multi-purposed elastomer which yields a balanced combination of properties. Neoprene o-rings are typically seen in the refrigeration sector, as they demonstrate remarkable resistance to chemicals such as ammonia and a variety of coolants. Neoprene o-rings also perform well in contact with oils and many chemicals and has good resistance to sun, ozone and weather. The material displays outstanding toughness and good resistance to fire.Performs well in Refrigerants, Ammonia, Water, Silicone grease and oils, High aniline point mineral oil.Does not perform well in Aromatic hydrocarbons, Ketones, Esters, Ethers, Strong oxidizing acids, Chlorinated hydrocarbons.
