Generic Buna-N O-Ring [3-1/4" ID] [3/16" CS] (O-653)

A Buna-N O-ring helps create a seal at a compatible circular sealing point, and this generic version is sized with a 3-1/4 inch inside diameter and 3/16 inch cross-section using the O-653 reference. When a thicker-profile O-ring becomes flattened or damaged, the assembly can lose the sealing 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 groove fill. 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 the original application calls for a heavier seal and the exact profile must be matched closely during service. That helps keep repairs more accurate and more reliable.

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