  • Prepare the Flange. Completely clean the surface to ensure optimal adhesion. Remove all oil, graphite, and other residue.
  • Measure and cut the gasket tape so the length is slightly oversized by 3 mm (1/8"). Perform a 90° butt cut at both ends.
  • Apply divider bar gasket
  • Remove the adhesive backing and firmly press the end of the gasket into the outer gasket. Lay the tape across the divider bar and firmly press the other end into the outer gasket.

ATTENTION: Divider bars in Heat Exchangers rarely operate at significant differential pressures, therefore, a butt cut pressed firmly into the outer flange gasket will provide an adequate and successful seal. Gore does not recommend any alternative cutting techniques or overlapping at the divider bar and circular gasket interface.
