Planisteel MJ

Composition

  • Cladding material: all types of steels and alloys
  • Available filler material
    • flexible graphite (standard filler)
    • PTFE
    • ceramic

Characteristics

Planisteel MJ metal-jacketed gaskets offer many advantages:

  • good sealing performance even with moderate tightening loads
  • dimensional stability over time
  • compatibility with numerous fluids (gases, vapours, oils, chemicals)
  • adaptability to standard and special flanges
  • resistance to high temperatures and medium-high pressures

  • good resistance to thermal shocks

  • greater robustness compared to soft gaskets

Planisteel MJ gaskets are available in different construction configurations (single or double jacket, with or without overlap lips) and can be customised according to diameter, thickness, jacket material and filler, depending on specific operating conditions.
