Generic Buna-N O-Ring [3" ID] [1/8" CS] (O-275)

A Buna-N O-ring helps create a seal at a compatible circular connection, and this generic version is sized with a 3 inch inside diameter and 1/8 inch cross-section using the O-275 reference. When an O-ring in this size becomes compressed, brittle, or cut, the assembly can lose the sealing support it should maintain.

The 1/8 inch cross-section gives this O-ring practical value because it provides a fuller sealing profile than thinner alternatives while remaining suitable for many standard groove designs. A properly selected O-ring helps support cleaner compression and contributes to more dependable sealing performance.

This type of part is especially useful during service work where the original seal dimensions must be matched accurately to restore correct fit and function. That makes it practical for targeted maintenance and repair.

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