Generic Buna-N O-Ring [6-1/2" ID] [3/32" CS] (90-423-5165)

A Buna-N O-ring helps create a seal at a compatible large circular connection, and this generic version is sized with a 6-1/2 inch inside diameter and 3/32 inch cross-section using the 90-423-5165 reference. When an O-ring with this profile becomes brittle, compressed, or cut, the assembly can lose the sealing support it should maintain.

The 3/32 inch cross-section gives this O-ring practical value because it provides a moderate profile for larger groove designs that do not call for a thinner specialty section or a heavier-duty alternative. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing performance.

This type of part is especially useful during service work where larger original seal dimensions are known and must be matched accurately for reliable reassembly. That keeps maintenance more precise and more dependable.

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