GB HST-250 Heat Shrink Tubing, 1/4 to 1/8 in Dia, 4 in L, Polyolefin, Black

Thin wall heat-shrink tubing is constructed from durable, flame-retardant black polyolefin which is resistant to both solvents and fluids making it ideal for cable insulation, repair, marking or bundling. Heat shrink not only provides superior mechanical, abrasion and moisture protection but also strengthens connections and provides a comfortable gripping surface. As a result, professional and DIY multi-purpose uses include repairing cords covering tool and sporting equipment handles and sealing rope for neat, unravel resistant ends. Finally, tubing capably resists common fluids and solvents. Upon heating to 120 deg C the tubing begins to shrink but will not drip, crack or flow and is self-extinguishing within 30 secs.
