    Buna O-Rings

    Buna O-Rings

    Buna O-Rings are the most common o-rings on the market. Ideal for water or hydrocarbons (Oil & Gas), they are a staple in the industry. In recent years gasoline formulations have been changed to reduce emmisions or reduce wear in engines.
    The additives used to accomplish this are NOT always compatible with Buna-N and has resulted in the auto industry upgrading o-rings to Viton® elastomers. Buna-N however is the least expensive o-ring material on the market so, it will continue to be the most often used in easy, low temperature (less than 225 F) mid Ph level appliacations.


    Buna O-Rings Description:

    Nitrile butadiene rubber (NBR) is a family of unsaturated copolymers of 2-propenenitrile and various butadiene monomers (1,2-butadiene and 1,3-butadiene). Although its physical and chemical properties vary depending on the polymer's composition of nitrile, this form of synthetic rubber is generally resistant to oil, fuel, and other chemicals (the more nitrile within the polymer, the higher the resistance to oils but the lower the flexibility of the material).
