MIL-LT Very flexible, flame-retardant, polyolefin heat-shrinkable tubing MIL-LT tubing is a very flexible, low-shrink-temperature, heatshrinkable product for a variety of military applications. It meets the requirements of AMS-DTL-23053/5, Classes 1 and 3, and is used for insulation, identification, strain relief, wire bundling, and color coding. MIL-LT tubing hot-stamps extremely well. Made from flame-retardant polyolefin, the tubing has excellent physical, chemical, and electrical properties that meet military requirements for highly reliable, general-purpose tubing. Only a few sizes of MIL-LT tubing are required to cover many substrate diameters.
