About General Purpose O-Rings

Take on a range of tasks such as sealing faucets, valves, and flanges with these multipurpose O-rings. They are available in different elastomers to provide the chemical resistances and physical properties needed for your application. All inch sizes conform to AS568 standards for dimensions and tolerances.

With excellent resistance to petroleum oils and gasoline, these Buna-N O-rings are a good choice for general use and low-pressure hydraulic and pneumatic seals. Buna-N, also known as nitrile rubber, is a strong, abrasion-resistant material that also offers good compression set resistance to minimize loss of resiliency.
