Frenzelit Compressed Gasket Sheet
Style 7095 - Novapress multi II Compressed Graphite Composite
Novapress multi II compressed graphite composite is Frenzelit's high temperature, high pressure compressed gasket material. This sheet's high content of pure graphite has given it over decades of successful use in the field. This material can withstand maximum temperatures in continuous operation, have a pH rating of 2-14 and have a non-stick coating that allows used gaskets to literally fall off the flange.
