Press-in-place seals are static face seals used in automotive and heavy duty applications to seal cast grooves. They have a rectangular cross-section that provides a large sealing contact area and compensates for surface imperfections in castings. Finite element analysis is used to simulate how the seals' self-retaining ribs create interference between the seal and groove wall. The manufacturer designs and cuts the seals for flexibility and to avoid defects from flashing or parting lines.

4. Common Applications
4
• Automotive and heavy duty industries
• Static applications where seals are located on
the face of the component

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.
