DESCRIPTION: GNA4000 is a blend of reinforcing materials and modified
nitrile latex, produced by the wet process, yielding a homogeneous
gasketing material. GNA4000 offers good torque retention and resistance
to crush. GNA4000 is recommended for use in exhaust manifold, egr
valve and other high temperature applications.
