PACKING MG 780

Expanded Mineral Graphite Packing, for all types of Equipment

  • The MG-780 packing is manufactured from the highest quality expanded pure mineral graphite, with corrosion inhibitor and carbon interior.
  • The advantages of pure expanded mineral graphite are its flexibility, compressibility and incombustibility; it is self-lubricating, compatible with most fluids and its storage period is unlimited.
  • Also available in the following versions:
    • ref. MG-780R: with API 607:589 fire test certificate
    • ref. MG-780RSM: idem the previous one and also SM lubrication.
    • ref. MG-780P: with Teflon® PTFE finish and impregnation.
    • ref. MG-780C: for valves and equipment with centrifugal and reciprocating movements.
  • In order to achieve greater resistance to pressure for use in valves and in conditions
    where clearances are greater than 0.35 mm, it is recommended to use braided anti-extrusion
    rings of graphite filament, our reference MG-420.

MG 780 Packing Applications

  • All kinds of Equipment Rotating and Static
  • Pumps , Valves, Agitators
  • Valves of tank bottom, inclined seat, butterfly or distributor
