Generic O-Ring [25-3/16" ID] [3/8" CS] O-340 (O-340)

An O-ring helps create a dependable seal at a compatible extra-large circular connection, and this generic version is sized with a 25-3/16 inch inside diameter and 3/8 inch cross-section using the O-340 reference. When a large heavy-profile O-ring becomes worn, flattened, or damaged, the assembly can lose the sealing support it should maintain around the full connection.

The 3/8 inch cross-section gives this O-ring practical value because very large sealing surfaces often require substantially more material than standard profiles can provide. A properly selected O-ring helps support cleaner groove fill and contributes to more dependable sealing performance in large-format applications.

This type of part is especially useful during major service work on extra-large lids, vessels, or housings where precise replacement dimensions matter to reliable closure. 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.
