Generic Buna-N O-Ring [2-11/16" ID] [3/32" CS] (O-631)

A Buna-N O-ring helps create a seal at a compatible circular sealing point, and this generic version is sized with a 2-11/16 inch inside diameter and 3/32 inch cross-section using the O-631 reference. When an O-ring with these dimensions becomes brittle, cut, or compressed, the connection can lose the sealing support it should maintain.

The 2-11/16 inch inside diameter gives this O-ring practical value because larger sealing points still depend on precise size matching for correct groove fit and compression. A properly selected O-ring helps support cleaner installation and contributes to more dependable sealing performance.

This type of part is especially useful during service work where the original seal dimensions are known and need to be matched closely for a reliable repair. That makes it practical for precise maintenance.

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