Generic Buna-N O-Ring [3" ID] [3/16" CS] (90-423-5337)

A Buna-N O-ring helps create a seal at a compatible circular sealing point, and this generic version is sized with a 3 inch inside diameter and 3/16 inch cross-section using the 90-423-5337 reference. When a thicker-profile O-ring becomes flattened or damaged, the connection 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 circular applications often need a more substantial sealing profile to achieve the intended contact and compression. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing performance.

This type of part is especially useful when replacing a heavier original seal where exact profile matching matters more than a general near-size substitute. That helps keep the repair accurate and more reliable.

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