FDA Approved VITON® O-Rings (FKM): Brown

The O-Ring Store LLC provides one of the largest range of O-Ring materials to meet the Food & Drug Administration’s (FDA) requirements for synthetic rubber compounds. Our Brown Viton FDA O-Rings conform to the Code of Federal Regulations section 177.2600.

Specifications Met:

  • ASTM D2000 - 99 Grade M6HK810 A1-10 B38 C12 C20 EF31 EO88
  • Viton Type 6 Grade A
  • Z1=Meets FDA 177.2600
  • Z2=Meets 3A Sanitary Class I requirements

3A Sanitary Approved Orings:

This standard is formulated by the International Association of Milk, Food and Environmental Sanitarians, U.S. Public Health Service, and the Dairy Industry Committee. These sanitary standards cover rubber materials intended for multiple-use as product contact surfaces or solution contact surfaces in the production, processing and handling of milk or milk products. Test procedures and criteria are also provided for rubber materials as a means of determining their ability to be cleaned and to receive effective bactericidal treatment or steam sterilization and to maintain their essential properties.    

Dupont-Dow Viton FDA Grade Viton O-Rings 75 Duro Brown:

Viton (Fluorocarbon,FKM) rubber has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. Low temperature resistance is normally not favorable and for static applications is limited to approximately –15°F (–26°C) although in certain situations it is suitable down to –40°F (–40°C). Under dynamic conditions, the lowest service temperature is between 5°F and 0°F (–15°C and –18°C). Gas permeability is very low and similar to that of butyl rubber.

Chemical Resistance:

  • Mineral oil and grease, low swelling in ASTM oil No. 1, and IRM 902 and IRM 903 oils
  • Hydraulic Oil, Petroleum Base
  • Non-flammable hydraulic fuels in the group HFD
  • Silicone oil and grease
  • Mineral and vegetable oil and grease
  • Aliphatic hydrocarbons (fuel, butane, propane, natural gas)
  • Aromatic hydrocarbons (benzene, toluene)
  • Chlorinated hydrocarbons (trichlorethylene and carbon tetrachloride)
  • Chlorine Water
  • Gasoline, Fuels, also fuels with methanol content
  • Liquefied Petroleum Gas (LPG)
  • Natural Gas
  • Propane
  • Diesel Oil
  • High vacuum
  • Very good ozone, weather and aging resistance.

Not Compatible With:

  • Glycol based brake fluids
  • Ammonia gas, amines, alkalis
  • Brake Fluid
  • Acetone
  • Superheated steam
  • Low molecular organic acids (formic and acetic acids)
  • Skydrol 500
  • Methyl Ethyl Ketone

Operating temperature: -20° to +400F°

Stock O-Rings in over 20 different compounds and durometers the following six are the standard rubber materials in a range of durometers (Shore A) hardness to satisfy practically any service condition:

Viton® O-Rings / FKM: Fluorocarbon (Viton®) exhibits exceptional resistance to chemicals, oils, temperature extremes (-13°F to +446°F), low compression set, low gas permeability and excellent aging characteristics. Applications include: aircraft engines, automotive fuel handling systems, and chemical processing industries. FKM is also suitable for high vacuum applications. It is not recommended for exposure to ketones, alkalis, and Skydrol® fluids. Custom compounds are available with improved chemical and low temperature resistance.

Buna-N O-Rings / Nitrile O-Rings / NBR: Nitrile (Buna-N) is the most widely used elastomer due to its excellent resistance to petroleum products, operating temperature range (-40°F to +257°F) and one of the best performance-to-cost values. It's an ideal material for aerospace, automotive, propane and natural gas applications. Special Hydrogenated Nitrile (HNBR) compounds can improve resistance to direct ozone, sunlight, and weather exposure while increasing temperature range to +300°F.

Ethylene-Propylene / EPDM O-Rings: EPDM has outstanding resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight (-40ºF to +275ºF); but it is not recommended for gasoline, petroleum oil and grease, and hydrocarbon environments. This popular rubber compound is usually the first choice for low torque drive belt applications.

Fluorosilicone O-Rings / FVMQ: Fluorosilicone (-75º to +400ºF) combines the good high and low temperature stability of silicones with the fuel, oil, and solvent resistance of fluorocarbons. FVMQ is unparalleled for aerospace fuel systems, auto fuel emission control systems and to meet or exceed government, military, aerospace, automotive, industrial and commercial specifications. However, due to relatively low tear strength, high friction and limited abrasion resistance of these materials, they are generally not used in dynamic applications. They are also not recommended for exposure to brake fluids, hydrazine, or ketones.

Silicone O-Rings / VMQ: In the Silicone family, you will find compounds which are superior as static seals in extreme temperature conditions. Standard compounds handle operating temperatures -85º to +400ºF. Silicone compounds are popular in food and medical applications because they are very clean and do not impart odor or taste. Special Phenyl silicones can be used down to -148°F.

Neoprene® O-Rings / CR: Neoprene (-40º to +250ºF) is reasonably priced and features good resistance to petroleum oils, ozone, sunlight and oxygen aging, relatively low compression set, good resilience and outstanding physical toughness. It is the preferred sealing material for the refrigeration industry because of its resistance to ammonia and Freon®.
