Generic Buna-N O-Ring [7-1/2" ID] [3/16" CS] (90-423-5367)

A Buna-N O-ring helps create a dependable seal at a compatible large circular connection, and this generic version is sized with a 7-1/2 inch inside diameter and 3/16 inch cross-section using the 90-423-5367 reference. When a larger heavier-profile O-ring becomes brittle, cut, or compressed, the assembly can lose the sealing support it should maintain.

The 3/16 inch cross-section gives this O-ring practical value because larger circular groove designs often depend on a more substantial profile than thinner sections can provide. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing performance where a thicker section is part of the original design.

This type of part is especially useful during maintenance where a large original seal must be replaced with a closely matched profile and diameter. That keeps repair work more accurate and more dependable.

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