About Press-in-place Seals Static face seals Rectangular cross section Self-retaining features 3
Common Applications • Automotive and heavy duty industries • Static applications where seals are located on the face of the component 4
Application Challenges • Surface imperfections in cast grooves create potential leak paths for fluid or dirt 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. Imperfections on cast metal surface 5
Sealing Mechanics • Rectangular geometry o Provides large sealing contact area o Compensates for surface imperfections in cast grooves Uncompressed 6 Compressed
Sealing Mechanics • Rectangular geometry o Dimensions can be customized independently o Optimally designed for shallow or deep grooves Shallow groove 7 Deep groove
Finite Element Analysis • Self-retaining features: ribs, nibs, bumps, etc. o Create interference between the groove wall and the seal 8 Finite Element Analysis Simulation
Finite Element Analysis Finite Element Analysis Animation 9
About the manufacturer • Parker’s TechSeal Division extrudes and precision cuts the press-in-place seals o Design flexibility o No flash / voids / parting lines 10
