Benefits of Vacuum Impregnation

Porosity is inherent to parts, and interconnect porosity may form a leak path. Unless sealed, this leak path will cause the part to fail if it needs to be pressure tight.

Vacuum impregnation seals internal leak paths, and allows a part to be pressure tight. The process allows manufacturers to use parts that would otherwise be scrapped.
