Generic O-Ring [31-1/2" ID] [5/16" CS] O-105 (O-105)

An O-ring helps create a dependable seal at a compatible very large circular connection, and this generic version is sized with a 31-1/2 inch inside diameter and 5/16 inch cross-section using the O-105 reference. When a very large heavy-profile O-ring becomes worn, flattened, or damaged, the assembly can lose the sealing support it should maintain around the full circumference.

The 5/16 inch cross-section gives this O-ring practical value because very large groove designs often need more sealing mass than standard lighter profiles can provide. A properly selected O-ring helps support cleaner groove fill and contributes to more dependable sealing performance in large vessel-style applications.

This type of part is especially useful during major service work where exact replacement of a very large original seal is important to restoring reliable closure. That keeps 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.
