    Auto Parts NBR O Rings Seal Excellent Wear Resistant and Oil Resistant

    Auto Parts NBR O Rings Seal Excellent Wear Resistant and Oil Resistant
    Advantage: excellent resistant to oil, second only to TR, ACM and FKM, better than other general rubber. Good heat resistance, good air tightness, abrasion resistance and water resistance, strong cohesive force.
    Disadvantage: poor cold resistance and ozone resistance, low strength and bad flexibility, poor acid resistance, bad electrical insulation and polar solvents resistance.
    Operating Temperature: about -40°C~+100°C.

    RUICHEN SEALING CO.,LTD offers the seal industry's largest inventory of o-rings, which includes every standard AS568 and ISO 3601 size, and the following:

    • Inside Diameter from 0.031 in (0.794 mm) to 26.0 in (66.04cm)
    • Outside Diameter from 0.094 in (2.38 mm) to 26.5 in (67.31cm)
    • Cross Section from 0.031 in (0.794 mm) to 0.250 in (6.35mm)

    Standard O-Ring Material Applications


    Nitrile (Buna-N) is the most widely used elastomer due to its excellent resistance to petroleum products, operating temperature range (-40°C to +100°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.


    ASTM D1418 Designation: NBR


    ASTM D2000/SAE J200 Type, Class: BF, BG, BK, CH


    ORK Compound Designation: BN


    Standard Color: Black


    Description: Presently the seal industry's most widely used and economical elastomer, Nitrile combines excellent resistance to petroleum-based oils and fuels, silicone greases, hydraulic fluids, water and alcohols, with a good balance of such desirable working properties as low compression set, high tensile strength, and high abrasion resistance.


    Key Use(s): Oil resistant applications of all types. Low temperature military uses. Off-road equipment. Automotive, marine, aircraft fuel systems. Can be compounded for FDA applications.


    Temperature Range


    Standard Compound: -40°C to +100°C

    Hardness (Shore A): 40 to 90.

    Features: Comprised of the copolymer butadiene and acrylonitrile, in varying proportions. Compounds can be formulated for service temperature ranging from -40°C to +100°C. Use of Carboxylated Nitrile can have superior abrasion resistance, while still having improved oil resistance.

    Limitations: Nitrile compounds are attached by small amounts of Ozone. Phthalate type plasticizers are commonly used in compounding Nitrile Rubber. These plasticizers can migrate out and cause problems with certain plastics. Also, new regulations on certain phthalates have limited their use.
