  3. 3. About Press-in-place Seals 3 Static face seals Rectangular cross section Self-retaining features
  4. 4. Common Applications 4 • Automotive and heavy duty industries • Static applications where seals are located on the face of the component
  5. 5. Application Challenges 5 • Surface imperfections in cast grooves create potential leak paths for fluid or dirt Imperfections on cast metal surface Cast grooves are typically used in automotive and heavy duty industries. Due to the nature of casting process, cast grooves usually have porosities on the metal surface.
