Compressed Sheet NOVATEC 925F Engineered Graphite NOVATEC's high percentage of graphite and low
percentage of rubber binder gives it such remarkable
media and temperature resistance that all other
compressed sheets is now obsolete. NOVATEC 925F is Frenzelit's universal high pressure
compressed sheet gasket material and it contains 75%
pure graphite. This is an excellent chemical sheet
that works best in flanges, pump casings, heat
exchangers, lids, vessels, valve bodies and sight
glasses. It can replace flexible graphite in many
applications. This sheet is easily identified by its
grape colored "easy release" non-stick coating.
Frenzelit's NOVATEC
Engineered Graphite easily replaces the competitions
compressed sheets. See our "Compressed Gasket Sheet
Comparison" for details. Our "Gasket Installation Procedure" must be followed to assure optimum performance in your gasket application. |
