Generic Tank Body O-Ring [18-7/8" ID] [5/16" CS] (O-498)

A tank body O-ring helps create a seal at a compatible large filter or vessel connection, and this generic version is sized with an 18-7/8 inch inside diameter and 5/16 inch cross-section using the O-498 reference. When a large tank seal becomes worn, flattened, or damaged, the housing can lose the sealing support it should maintain.

The large-diameter heavy-profile construction gives this O-ring practical value because tank body seals often require more material than standard profiles to support dependable closure. A properly selected replacement helps support cleaner groove fill and contributes to more dependable tank sealing performance.

This type of part is especially useful during major service when the tank body is opened and the original seal should be renewed before reassembly. That helps keep maintenance more focused and more dependable.

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