Generic Buna-N O-Ring [3-3/8" ID] [3/16" CS] (O-654)

A Buna-N O-ring helps create a dependable seal at a compatible circular connection, and this generic version is sized with a 3-3/8 inch inside diameter and 3/16 inch cross-section using the O-654 reference. When a larger heavier-profile O-ring becomes flattened, cut, or worn, 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 thinner profile can provide. A properly selected O-ring helps support cleaner compression and contributes to more dependable sealing performance in the intended application.

This type of part is especially useful during repair work where the original seal dimensions and thickness need to be matched accurately to restore reliable operation. That helps keep maintenance precise and more dependable.

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