Generic Buna-N O-Ring [7-1/4" ID] [3/16", CS] (90-423-5366)

A Buna-N O-ring helps create a seal at a compatible large circular connection, and this generic version is sized with a 7-1/4 inch inside diameter and 3/16 inch cross-section using the 90-423-5366 reference. When a heavier-profile O-ring becomes flattened, brittle, or damaged, the assembly can lose the sealing support it should maintain under normal service conditions.

The 3/16 inch cross-section gives this O-ring practical value because larger sealing points often need more material than a lighter profile can provide. A properly selected O-ring helps support cleaner groove fill and contributes to more dependable sealing performance where a substantial profile is required.

This type of part is especially useful when replacing an original large-diameter seal that depends on a thicker section for proper groove compression. That keeps maintenance more precise and more dependable.

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