Generic Buna-N O-Ring [3/16" ID] [1/8" CS] (90-423-5201)

A Buna-N O-ring helps create a seal at a compatible small circular connection, and this generic version is sized with a 3/16 inch inside diameter and 1/8 inch cross-section using the 90-423-5201 reference. When a compact O-ring becomes brittle, cut, or worn, the small sealing point can lose the support it should maintain.

The very small inside diameter gives this O-ring practical value because compact sealing applications still depend on precise dimensional matching to fit the groove and compress correctly. A properly selected O-ring helps support cleaner installation and contributes to more dependable sealing performance.

This type of part is especially useful in small fluid, air, or control applications where exact profile and diameter matter more than broad interchangeability. That makes it practical for detailed service work.

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