Generic Buna-N O-Ring [5-3/8" ID] [1/8" CS] (O-368)

A Buna-N O-ring helps create a seal at a compatible larger circular connection, and this generic version is sized with a 5-3/8 inch inside diameter and 1/8 inch cross-section using the O-368 reference. When an O-ring with these dimensions becomes brittle, cut, or flattened, the assembly can lose the sealing support it should maintain.

The 1/8 inch cross-section gives this O-ring practical value because it provides a reliable mid-profile option for larger groove designs without requiring the added material of a thicker seal. A properly selected O-ring helps support cleaner compression and contributes to more dependable sealing performance.

This type of part is especially useful during routine maintenance when a larger original seal must be matched accurately to preserve correct fit. That keeps repairs more precise and more dependable.

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