Generic Buna-N O-Ring [12-1/2" ID] [1/4" CS] (O-480)

A Buna-N O-ring helps create a seal at a compatible large-diameter circular connection, and this generic version is sized with a 12-1/2 inch inside diameter and 1/4 inch cross-section using the O-480 reference. When a large O-ring becomes worn, stretched, or compressed, the assembly can lose the broad sealing support it should maintain.

The substantial 1/4 inch cross-section gives this O-ring practical value because larger sealing surfaces often require more material to achieve the intended compression and closure. A properly selected O-ring helps support cleaner sealing and contributes to more dependable performance in large-format applications.

This type of part is especially useful in lids, tanks, housings, or other larger circular assemblies where the original seal dimensions must be matched closely. That keeps repairs more accurate and more reliable.

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