Generic Buna-N Square Ring [2-3/8" ID] [2-9/16" OD] (90-423-6167)

A Buna-N square ring helps create a seal at a compatible circular connection where the original design uses a square-profile seal rather than a round O-ring, and this generic version is sized with a 2-3/8 inch inside diameter and 2-9/16 inch outside diameter using the 90-423-6167 reference. When a square-profile seal becomes damaged or flattened, the assembly can lose the sealing support it should maintain.

The square-ring profile gives this part practical value because profile-specific seals work best when the replacement matches both the shape and dimensions of the original design. A properly selected square ring helps support cleaner seating and contributes to more dependable sealing performance in the intended groove.

This type of part is especially useful during service work where exact seal profile matching is important and a standard round O-ring is not the intended replacement. That helps keep repairs more precise and more dependable.

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