Heat shielding fire sleeve is fabricated from a dense E-glass fiberglass with a thick coating of self-extinguishing high temperature silicone rubber which is engineered to protect hoses, cables and wire harness from damage due to exposure to extreme heat, open flame and molten splash. It also provides a high degree of insulation value, protecting hot, cold or cryogenic lines, pipes and tubing from heat or cold loss, providing energy savings and abrasion resistance.
