Generic Buna-N O-Ring [7-3/4" ID] [1/8" CS] (90-423-5265)

A Buna-N O-ring helps create a dependable seal at a compatible large circular connection, and this generic version is sized with a 7-3/4 inch inside diameter and 1/8 inch cross-section using the 90-423-5265 reference. When an O-ring of this size becomes worn or compressed, the assembly can lose the sealing support it should maintain across the connection.

The 1/8 inch cross-section gives this O-ring practical value because it offers a balanced sealing profile for larger applications where a heavy-duty section is not required. A properly selected O-ring helps support cleaner compression and contributes to more dependable sealing performance in the intended groove.

This type of part is especially useful during maintenance where a larger original seal needs to be matched closely in both diameter and profile. 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.
