Generic Buna-N O-Ring [11/16" ID] [1/8" CS] (90-423-7209)

A Buna-N O-ring helps create a dependable seal at a compatible circular connection, and this generic version is sized with an 11/16 inch inside diameter and 1/8 inch cross-section using the 90-423-7209 reference. When an O-ring with this profile becomes flattened, brittle, or worn, the connection can lose the sealing support it should maintain.

The 1/8 inch cross-section gives this O-ring practical value because not every 11/16 inch inside diameter application uses the same sealing thickness. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing where a slightly fuller profile is required.

This type of part is especially useful during targeted maintenance when the original dimensions are known and seal profile matters just as much as inside diameter. That helps keep repairs accurate and better matched to the original design.

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