Generic Buna-N O-Ring [5-5/8" ID] [5/16" CS] (90-423-6128)

A Buna-N O-ring helps create a seal at a compatible large circular connection, and this generic version is sized with a 5-5/8 inch inside diameter and a substantial 5/16 inch cross-section using the 90-423-6128 reference. When a large heavy-profile O-ring becomes flattened, cut, or worn, the assembly can lose the sealing support it should maintain across the full circumference.

The 5/16 inch cross-section gives this O-ring practical value because some larger sealing surfaces require more material than standard sections 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 restoring an original seal in a larger assembly that depends on a heavier cross-section for correct operation. That keeps service more accurate and more dependable.

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