Generic O-Ring [3" ID] [3/16" CS] O-109 (O-109)

An O-ring helps create a dependable seal at a compatible circular connection, and this generic version is sized with a 3 inch inside diameter and 3/16 inch cross-section using the O-109 reference. When a thicker-profile O-ring becomes brittle, compressed, or damaged, the connection can lose the sealing support it should maintain under normal service conditions.

The 3/16 inch cross-section gives this O-ring practical value because some applications require more sealing material than a lighter section can provide. A properly selected O-ring helps support cleaner groove fill and contributes to more dependable sealing performance where a substantial profile is specified.

This type of part is especially useful during maintenance where the original seal design calls for a thicker profile and accurate matching is important to dependable service. That keeps repairs more precise and more dependable.

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