Generic Square Ring [2-1/8" ID] [2-7/16" OD] (O-435)

A square ring helps create a seal at a compatible circular connection where a flat-sided profile is required, and this generic version is sized with a 2-1/8 inch inside diameter and 2-7/16 inch outside diameter using the O-435 reference. When a square-profile seal becomes worn, cut, or flattened, the assembly can lose the sealing support it should maintain.

The square-ring design gives this part practical value because some applications rely on a specific seal shape rather than a standard round O-ring. A properly selected square ring helps support cleaner seating and contributes to more dependable sealing performance where the original groove is profile-specific.

This type of part is especially useful during maintenance where exact replacement of the original seal shape is important to dependable reassembly. That keeps service work more precise and more dependable.

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