Generic Buna-N O-Ring [8-1/4" ID] [1/8" CS] (90-423-5267)

A Buna-N O-ring helps create a dependable seal at a compatible large circular connection, and this generic version is sized with an 8-1/4 inch inside diameter and 1/8 inch cross-section using the 90-423-5267 reference. When an O-ring of this size becomes brittle, worn, or flattened, 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 balanced sealing profile for larger groove designs that do not require a thick heavy-duty section. A properly selected O-ring helps support cleaner compression and contributes to more dependable sealing performance in the intended application.

This type of part is especially useful during service work where the original large-diameter seal dimensions need to be matched accurately for reliable reassembly. That makes replacement more precise and more dependable.

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