Generic Buna-N O-Ring [1-3/8" ID] [1/8" CS] (90-423-7220)

A Buna-N O-ring helps create a seal at a compatible circular sealing point, and this generic version is sized with a 1-3/8 inch inside diameter and 1/8 inch cross-section using the 90-423-7220 reference. When an O-ring in this size becomes cut, compressed, or brittle, the connection can lose the sealing support it should maintain.

The 1-3/8 inch diameter and 1/8 inch cross-section give this O-ring practical value because successful sealing depends on matching both the groove size and the intended compression range. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing performance.

This type of part is especially useful in maintenance work where the original O-ring dimensions are known and a precise replacement is required rather than a general approximation. That helps keep repairs accurate and more dependable.

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