Generic Buna-N O-Ring [2-1/8" ID] [1/16" CS] (O-320)

A Buna-N O-ring helps create a seal at a compatible circular connection, and this generic version is sized with a 2-1/8 inch inside diameter and 1/16 inch cross-section using the O-320 reference. When a slimmer-profile O-ring becomes brittle, compressed, or damaged, the sealing point can lose the support it should maintain.

The 1/16 inch cross-section gives this O-ring practical value because some applications require a lighter profile for the groove to seat and compress correctly. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing where a thin section is specified.

This type of part is especially useful when restoring a seal that depends on exact groove dimensions and a slimmer profile rather than a thicker general-purpose substitute. That makes it practical for precision repair work.

Installed in the proper application, this O-ring helps support dependable sealing and contributes to cleaner overall assembly performance.
