The fire retardant sleeve is made from dense fiberglass E-glass with a thick coating of self-extinguishing high temperature silicone rubber that is designed to protect hoses, cables and wiring harnesses from damage due to exposure to extreme temperatures, open flames and molten metal splashes.
Fire resistant hoses also provide a high degree of insulation, protecting hot or cold or cryogenic lines, pipes and piping from heat or cold loss, providing energy savings and abrasion resistance.
