GRAPHITE PACKING
Menu
Spec. TU 2573-002-93978201-2008
Graphite packing is made from thermally expanded graphite (TRG) ribbon with addition of reinforcing filaments.
Types
NG-300 packing is made from thermally expanded graphite yarn reinforced with fiberglass. It shows a high thermal and chemical resistance and elasticity. It has a low friction coefficient, does not damage shafts, piston-rods and valves.

NG -200 is mainly intended for use in sealing of gland joints of high pressure armature. Owing to its softness and compressibility, the NG-200 packing ensures good sealing at relatively low loads, which makes it ideal for sealing the drive armature.
