O-Ring, Buna-N

O-rings are circular sealing rings that have a round cross section and look the letter "O." Used in a variety of axial, radial static and dynamic applications, they are available in several different materials: Buna-N and Viton® are two that are very common. Buna-N is popular because of its low cost, physical properties and resistance to certain chemicals and has an operating temperature range of -40° to +250°F. Viton® offers extended resistance to petroleum oils at high operating temperatures; its operating range is -15° to +400°F. A common durometer (hardness) rating for Buna-N is 70 and the base rating for Viton® is 75. O-ring size is typically specified as inside diameter (ID) and cross section (CS) diameter, which is also referred to as width. (Listed by increasing cross section and inside diameter.)
