Express Sleeves are exactly what our customers have been looking for. The easy to use sleeving is a combination of a high temperature insulation material to a highly reflective Mylar foil with a hook and loop closure. The sleeving is designed to provide maximum protection for wires, hoses, and cables from the very damaging effect of radiant heat with an easy application. Simply pull apart the material, wrap around the wire, and re-close the sleeving. Express Sleeves reflect over 90 percent of radiant heat up to 2000 degrees Fahrenheit. It is also fireproof, fire resistant, and just looks good. Express Sleeves come in 2 sizes: 1/2 inch to 1 inch and 1 inch to 1 1/2 inch in diameter and in 3 foot, 12 foot, and 50 foot lengths. Express Sleeve is also available in custom widths and lengths for special applications.
