Originally developed for the military, this high quality self-bonding silicone wrap forms a permanent non-conductive, air and watertight insulating seal which stays flexible and won’t crack or melt in temperatures from –60° to 500°F. It can be removed and won’t leave a sticky residue like electrical tape. A great coolant hose patch, electric insulator or tool handle wrap. One 1"×10' roll, 2.0 oz.
