Metric Buna-N O-Rings

Metric O-Ring

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 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. A common durometer (hardness) rating for Buna-N is 70. O-ring size is typically specified as inside diameter (ID) and cross section (CS) diameter or width. (Listed by increasing cross section and inside diameter.)
