Generic Buna-N O-Ring [1-5/16" ID] [3/32" CS] (O-303)

A Buna-N O-ring helps create a seal at a compatible circular connection, and this generic version is sized with a 1-5/16 inch inside diameter and 3/32 inch cross-section using the O-303 reference. When an O-ring of this size becomes worn or distorted, the connection can lose the sealing support it should maintain.

The 3/32 inch cross-section gives this O-ring practical value because it offers a balanced profile between thinner and thicker alternatives for applications that require more precise groove fill. A properly selected O-ring helps support cleaner compression and contributes to more dependable sealing performance.

This type of part is especially useful during maintenance work where both the inside diameter and the original cross-section must be matched closely to restore the intended seal. That helps keep repairs accurate and more dependable.

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