Generic Buna-N Square Ring [6-9/16" ID] [6-13/16" OD] (O-264)

A Buna-N square ring helps create a dependable seal at a compatible large circular connection where a square-profile seal is required, and this generic version is sized with a 6-9/16 inch inside diameter and 6-13/16 inch outside diameter using the O-264 reference. When a square-profile seal becomes brittle, flattened, or damaged, the assembly can lose the sealing support it should maintain around the connection.

The square-ring profile gives this part practical value because some larger groove designs depend on a specific seal shape rather than a round cross-section. A properly selected square ring helps support cleaner seating and contributes to more dependable sealing performance where the original design calls for that profile.

This type of part is especially useful during maintenance where exact square-ring dimensions must be matched closely for reliable reassembly. That helps keep the repair precise and more dependable.

Installed in the proper application, this square ring helps support dependable sealing and contributes to cleaner overall system integrity.
