Generic Buna-N O-Ring [15-15/16" ID] [5/16" CS] (90-423-6115)

A Buna-N O-ring helps create a seal at a compatible large-diameter circular connection, and this generic version is sized with a 15-15/16 inch inside diameter and a substantial 5/16 inch cross-section using the 90-423-6115 reference. When a large-profile O-ring becomes worn, stretched, or compressed, the assembly can lose the sealing support it should maintain around the full circumference.

The heavier 5/16 inch cross-section gives this O-ring practical value because large sealing surfaces often require more material to achieve the intended compression and contact area. A properly selected O-ring helps support cleaner fit and contributes to more dependable sealing performance in broad circular applications.

This type of part is especially useful in larger lids, tanks, housings, or vessel assemblies where exact seal dimensions must be matched closely to restore reliable closure. That keeps replacement work accurate and more dependable.

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