4.81 out of 5 stars 91 Customer Reviews

DEI Heat Sheath sleeves are made from high-temperature fiberglass fabric bonded to aluminized material and then sewn into a tube. Designed to slide over wires and hoses, these sheaths can be easily shaped to fit the tightest bends. They will reflect up to 90 percent of the radiant heat and can insulate against up to 500 degrees of direct, continuous heat. They can be easily cut to length with scissors or a sharp knife and come in five popular diameters from 3/4 in. to 1 1/4 in., in 3 ft. lengths. They are also available in bulk, up to 50 ft. rolls.
