Heat Shrinkable Cable sealing cap 
 Radiation crosslinked heat shrinkable sealing cap for the end of waterproof wire and cable, insulation and protective treatment. Port-side coated with high performance hot melt adhesive, sealing cap can shrink when heated, while the glue melt, bonding the cable close the surface, play a good waterproofing, insulation and protective effect. Standard color is black.
