Generic O-Ring [8-1/4" ID] [3/8" CS] O-338 (O-338)

An O-ring helps create a dependable seal at a compatible large circular connection, and this generic version is sized with an 8-1/4 inch inside diameter and 3/8 inch cross-section using the O-338 reference. When a large heavy-profile O-ring becomes worn, flattened, or damaged, the connection 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 some large groove designs require substantially more sealing material than standard profiles can provide. A properly selected O-ring helps support cleaner groove fill and contributes to more dependable sealing performance where a substantial section is necessary.

This type of part is especially useful during major service work where the original seal depends on a heavier cross-section and exact sizing matters to reliable reassembly. That helps keep 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.
