Constructed from a high bulk fiberglass sleeve heavily coated with iron oxide red silicone rubber

  • Ideal for protecting hoses and cables in steel mills, aluminum smelting plants, offshore drilling rigs, foundries and glass manufacturing facilities
  • Ability to shed molten metal splash and withstand intense radiant heat
  • Excellent modulus of elasticity, allowing to easily stretch and expand over fittings and connectors
  • Resistance to most industrial chemicals and hydraulic oils
  • Reduces heat energy loss and environmental overheating
  • Unlimited shelf life
  • Pyrojacket's insulation properties allow it to provide effective burn protection for personnel from hot hoses and piping, while reducing costly heat energy losses.


Both Pyrojacket and Pyrotape retain their flexibility at minus 65°F (-54°C)
and they withstand 500°F (260°C) continuously, up to 2000°F (1090°C)
for 15-20 minutes. and up to 3000°F (1650°C) for 15-30 seconds.
