Generic Buna-N O-Ring [5/16" ID] [1/16" CS] (O-445)

A Buna-N O-ring helps create a seal at a compatible compact circular connection, and this generic version is sized with a 5/16 inch inside diameter and 1/16 inch cross-section using the O-445 reference. When a smaller slim-profile O-ring becomes worn or compressed, the connection can lose the sealing support it should maintain.

The 1/16 inch cross-section gives this O-ring practical value because some compact sealing points require a lighter profile for correct groove fit and compression. A properly selected O-ring helps support cleaner installation and contributes to more dependable sealing performance in small applications.

This type of part is especially useful when restoring a compact seal where exact dimensions matter more than broad interchangeability. That keeps repairs more accurate and more reliable.

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