Generic Buna-N O-Ring [5-3/8" ID] [1/4" CS] (O-18)

A Buna-N O-ring helps create a dependable seal at a compatible larger circular connection, and this generic version is sized with a 5-3/8 inch inside diameter and 1/4 inch cross-section using the O-18 reference. When a larger heavy-profile O-ring becomes worn or compressed, the assembly can lose the sealing support it should maintain.

The 1/4 inch cross-section gives this O-ring practical value because broad sealing areas often need a more substantial profile for proper groove fill and contact pressure. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing performance in the intended application.

This type of part is especially useful when replacing an original large-diameter seal where a heavier section is required for correct performance. That makes it practical for accurate service and rebuild work.

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