Generic Buna-N O-Ring [2-7/8" ID] [3/16" CS] (O-650)

A Buna-N O-ring helps create a seal at a compatible circular connection, and this generic version is sized with a 2-7/8 inch inside diameter and 3/16 inch cross-section using the O-650 reference. When a heavier-profile O-ring becomes worn or flattened, the sealing point can lose the support it should maintain.

The 3/16 inch cross-section gives this O-ring practical value because larger sealing points often require a more substantial profile to provide the intended compression and contact area. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing performance in the intended application.

This type of part is especially useful when replacing an original heavier-profile O-ring where exact groove fill matters to reliable service. That helps keep maintenance more accurate and more dependable.

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