  • The capacity to handle vacuum applications in temperatures up to 500°F or 206°C.
  • A PTFE core to reduce friction, while minimizing pressure drops and deposits.
  • Improved vacuum resistance at higher temperatures, greater kink resistance and reduced permeation.
  • A stainless steel or polypropylene braid.  
  • Inner diameters from ½ up to 4 inches.  
  • Accessories that can include fire sleeves, spring guards or heat shrinking for color coding.  
  • Availability of static-dissipative assemblies.
