Generic Buna-N O-Ring [8-1/4" ID] [3/16" CS] (90-423-5370)

A Buna-N O-ring helps create a seal at a compatible large circular connection, and this generic version is sized with an 8-1/4 inch inside diameter and 3/16 inch cross-section using the 90-423-5370 reference. When a larger heavier-profile O-ring becomes worn, cut, or compressed, the assembly can lose the sealing support it should maintain.

The 3/16 inch cross-section gives this O-ring practical value because broader sealing points often require more material than a lighter seal profile can provide. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing performance where a substantial section is part of the original design.

This type of part is especially useful when replacing an original larger seal that depends on a thicker profile for correct groove compression. That keeps 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.
