Generic O-Ring [3-1/2" ID] [3/16" CS] (O-442)

An O-ring helps create a dependable seal at a compatible circular connection, and this generic version is sized with a 3-1/2 inch inside diameter and 3/16 inch cross-section using the O-442 reference. When a thicker-profile O-ring becomes compressed, cut, 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 larger groove designs 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 required.

This type of part is especially useful during maintenance where the original seal uses a heavier cross-section and exact matching is important to dependable reassembly. That makes repairs more accurate and more dependable.

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