Generic Buna-N O-Ring [1/4" ID] [1/16" CS] (O-186)

A Buna-N O-ring helps create a seal at a compatible circular sealing point, and this generic version is sized with a 1/4 inch inside diameter and 1/16 inch cross-section using the O-186 reference. When a compact O-ring becomes brittle, flattened, or damaged, the connected fitting can lose the sealing support it should maintain.

The smaller 1/4 inch inside diameter gives this O-ring practical value because small sealing points require close dimensional accuracy rather than a near substitute. A properly selected O-ring helps support cleaner sealing and contributes to more dependable assembly integrity.

This type of part is especially useful in smaller fluid, air, or control applications where exact sealing dimensions are important to performance. That makes it practical for targeted service work.

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