Generic Buna-N O-Ring [9-3/4" ID] [1/8" CS] (90-423-5273)

A Buna-N O-ring helps create a dependable seal at a compatible large circular connection, and this generic version is sized with a 9-3/4 inch inside diameter and 1/8 inch cross-section using the 90-423-5273 reference. When a large O-ring in this size becomes worn, compressed, or brittle, 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 balanced sealing profile for large groove designs that do not require an unusually heavy section. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing performance in the intended application.

This type of part is especially useful during maintenance where the original large-diameter seal must be matched closely to restore correct groove fit. That helps keep repairs more accurate and more dependable.

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