Metal-jacketed gaskets Planisteel MJ are sealing elements designed for industrial applications, especially for heat exchangers, where high reliability is required.

They consist of an external metal jacket enclosing a plastic or compressible filler material, combining the mechanical strength of metal with the adaptability properties of the filler.

 

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.

 

Planisteel MJ metal-jacketed gaskets are specifically designed for applications on heat exchangers and represent a reliable and versatile solution for plants in the chemical, petrochemical, energy, food and general plant engineering sectors, where safe sealing combined with long service life is required.
