Generic Buna-N O-Ring [9" ID] [1/4" CS] (O-191)

A Buna-N O-ring helps create a dependable seal at a compatible large circular connection, and this generic version is sized with a 9 inch inside diameter and 1/4 inch cross-section using the O-191 reference. When a large heavy-profile O-ring becomes flattened, damaged, or worn, the assembly can lose the sealing support it should maintain across the full circumference.

The 1/4 inch cross-section gives this O-ring practical value because larger sealing surfaces often need more material than a thinner profile can provide. A properly selected O-ring helps support cleaner groove fill and contributes to more dependable sealing performance in broad circular applications.

This type of part is especially useful when servicing larger housings, lids, or tanks where the original seal must be matched accurately in both size and section. That helps keep maintenance more precise and more dependable.

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