is a reliable, flame-retardant polyolefin tubing that provides electrical insulation and mechanical protection from wire, cable and components. It features an inner wall adhesive lining that shrinks upon application of heat, creating an environmental seal and strain relief around wires, connections and terminals. It is ideal for applications requiring moisture, chemical and temperature resistance. The Sleeves 3/32 to 5/8 in manufactured by HellermannTyton provide insulation to wire connectors and other electrical components while they are enclosed in a flame-retardant, thermoplastic alloy material. They feature a self-wrapping, easy-to-install design that offers flexibility and protection. They shrink tightly to fit the object when heated which helps seal out dirt, moisture, and other contaminates.
