Generic Buna-N O-Ring [6-1/2" ID] [1/8" CS] (O-277)

A Buna-N O-ring helps create a dependable seal at a compatible large circular connection, and this generic version is sized with a 6-1/2 inch inside diameter and 1/8 inch cross-section using the O-277 reference. When an O-ring with these dimensions becomes worn, flattened, or damaged, the assembly can lose the sealing support it should maintain.

The 1/8 inch cross-section gives this O-ring practical value because it offers a balanced sealing profile for larger applications that do not require an unusually thin or heavy section. A properly selected O-ring helps support cleaner compression and contributes to more dependable sealing performance in the intended groove.

This type of part is especially useful during maintenance where a larger original seal must be matched closely in both diameter and profile. That makes replacement work more accurate and more dependable.

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