Generic Buna-N O-Ring [3-1/8" ID] [3/16" CS] (O-652)

A Buna-N O-ring helps create a seal at a compatible circular sealing point, and this generic version is sized with a 3-1/8 inch inside diameter and 3/16 inch cross-section using the O-652 reference. When a thicker-profile O-ring becomes worn or compressed, 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 some larger sealing points require a more substantial profile to provide the intended contact area and compression. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing performance where a heavier section is required.

This type of part is especially useful when the original equipment design calls for a thicker seal and exact profile matching matters during service. That keeps the repair more accurate and more reliable.

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