Generic O-Ring [1-1/4" ID] [3/16" CS] (O-403)

An O-ring helps create a dependable seal at a compatible circular connection, and this generic version is sized with a 1-1/4 inch inside diameter and 3/16 inch cross-section using the O-403 reference. When a heavier-profile O-ring becomes brittle, flattened, or damaged, the connection can lose the sealing support it should maintain.

The 3/16 inch cross-section gives this O-ring practical value because some applications require a more substantial profile than thinner sections can provide. A properly selected O-ring helps support cleaner groove fill and contributes to more dependable sealing performance where a thicker profile is part of the original design.

This type of part is especially useful during service work where exact groove fit and original cross-section must be matched closely to restore reliable operation. That helps keep 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.
