Generic Buna-N O-Ring [5-1/8" ID] [1/4" CS] (O-384)

A Buna-N O-ring helps create a seal at a compatible large circular connection, and this generic version is sized with a 5-1/8 inch inside diameter and 1/4 inch cross-section using the O-384 reference. When a larger heavy-profile O-ring becomes flattened, damaged, or worn, the assembly can lose the sealing support it should maintain.

The 1/4 inch cross-section gives this O-ring practical value because broader sealing points often require a more substantial profile to provide the intended groove fill and compression. A properly selected O-ring helps support cleaner contact and contributes to more dependable sealing performance in larger circular applications.

This type of part is especially useful when replacing an original large-diameter seal that depends on a heavier profile for correct operation. That makes it practical for precise maintenance and rebuild work.

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