NOVATEC Premium Engineered Graphite with Kevlar®
 

Compressed Sheet

This ultimate composition of graphite and Kevlar® offers complete new product qualities and easily outperforms any of the competition’s non-metallic gasket material.  Primarily due to the high percentage of graphite used, it’s resistance to media and temperature is remarkable.  NOVATEC Premium offers excellent long term stability and its resistance to stress relaxation exceeds the values of all conventional materials.  This high density and high tensile strength enhance the NOVATEC Premium by offering excellent torque retention and superior sealability.

Color coded “Royal Blue” anti-stick surface is standard.
