Generic Buna-N O-Ring [7" ID] [1/8" CS], O-328 (O-328)

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 inch inside diameter and 1/8 inch cross-section using the O-328 reference. When an O-ring with these dimensions becomes brittle, worn, or flattened, the assembly can lose the sealing support it should maintain.

The 1/8 inch cross-section gives this O-ring practical value because it offers a balanced sealing profile for larger applications where a heavier-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 large original seal must be replaced with a closely matched dimensional equivalent. That keeps service more accurate and more dependable.

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