Lay Orientation for Metallic Seals

Lay orientation is integral to the optimal performance of metallic seals. So, what is lay orientation? When talking about surface finish, the term “lay” refers to the direction of the predominant surface pattern as a result of the production method used to machine the surfaces. There are many lay patterns, and metallic seals require a concentric or phonographic lay. Both lays ensure minimal leak paths across the seal track from tooling marks.
