Generic Buna-N O-Ring [5-7/8" ID] [1/4" CS] (O-218)

A Buna-N O-ring helps create a seal at a compatible large circular sealing point, and this generic version is sized with a 5-7/8 inch inside diameter and 1/4 inch cross-section using the O-218 reference. When a larger heavy-profile O-ring becomes brittle, 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 larger groove designs often need a fuller profile to achieve the intended compression and contact area. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing performance in broader circular applications.

This type of part is especially useful when replacing an original large-diameter seal that depends on a heavier section for reliable service. That helps keep the repair accurate and more dependable.

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