As we&#;ve discussed in past entries on this blog, O-Rings can come in a variety of sizes and have a wide range of uses.

With competitive price and timely delivery, xtnbk sincerely hope to be your supplier and partner.

They can also be made from a number of different substances. Here&#;s a guide to the kinds of O-Ring materials we use, how they are used, and when to avoid using them.

Nitrile (Buna, NBR): A widely used, economical material that has strong wear resistance and mechanical properties.

• Temperature: -55 to 250 degrees Fahrenheit
• Applications: Petroleum based oils and fuels, dynamic applications
• Avoid: Brake fluids and ozone

Hydrogenated Nitrile (HNBR): Nitrile base with added chemical strength and resistance following hydrogenation.

• Temperature: -50 to 300 degrees Fahrenheit
• Applications: Water and steam up to 300 degrees Fahrenheit, fuel systems, oil resistant and high abrasion applications
• Avoid: Strong acids and polar solvents such as ethers and ketones

Polyacrylate (ACM): Widely used by auto makers in power steering and transmission systems.

• Temperature: -15 to 350 degrees Fahrenheit
• Applications: Mineral oil, engines, gear boxes, power steering, transmissions
• Avoid: Cold temperatures, hot water, steam

Ethylene-Propylene (EPDM): Strong ozone and chemical resistance

• Temperature: -55 to 275 degrees Fahrenheit, 300 degrees Fahrenheit when used with peroxide curing agents
• Applications: Brake systems, glycol-based fluids, H20 steam
• Avoid: Mineral oil products and hydrocarbon fluids

Chloroprene (Neoprene, CR): The first commercial synthetic rubber developed, chloroprene has good mechanical properties over a wide range of temperatures.

• Temperature: -40 to 250 degrees Fahrenheit
• Applications: Refrigeration, due to its excellent ozone resistance, low-temp H20
• Avoid: Esters, ketones and aromatic and chlorinated hydrocarbons.

Butyl: An all-petroleum compound, butyl has low gas permeability and good resistance to sun exposure and ozone.

• Temperature: -70 to 400 degrees Fahrenheit
• Applications: Life science and medical devices, FDA applications, numerous specialized compounds for specific material certifications
• Avoid: Highly abrasive applications and water and steam over 250 degrees Fahrenheit

Fluorosilicone (FVMQ): Broad temperature performance and strong fuel and solvent resistance, but weak abrasion resistance due to high friction.

• Temperature: -75 to 400 degrees Fahrenheit
• Applications: Aerospace, fuel and mineral oil
• Avoid: High temperature air, dynamic applications

Fluorocarbon (Viton, FKM): The high fluorine levels in fluorocarbon rings give them excellent swelling and permeability resistance. They also feature high temperature and chemical resistance.

• Temperature: -15 to 400 degrees Fahrenheit
• Applications: Broad chemical resistance, transmission and blended gasoline
• Avoid: Low temperatures, ketones and amines

Tetrafluoroethylene-Propylene (AFLAS): Excellent chemical and temperature performance.

• Temperature: 15 to 450 degrees Fahrenheit
• Applications: Aerospace, steam, hot water, oil fields
• Avoid: Chlorinated hydrocarbons, ketones, acetic acid

Perfluoelastomer (FFKM): Of all elastomers, this one has the highest performing temperature and chemical properties, as well as low out-gassing and extractable properties.

• Temperature: -15 to 600 degrees Fahrenheit
• Applications: Semiconductors, chemical processing, vacuum applications
• Avoid: Fluorinated solvents and perfluorinated lubricants
