Key specifications
Brand: DELOCK
Manufacturer part number (MPN): 20663
EAN: 4043619206636
Material: Polyolefin
Colour: Black
Shrinkage ratio: 2:1
How to use
Slide the appropriate length of heat shrink tube over the cable or connection so it fully covers the area to be insulated. Apply heat evenly using a hot air gun, heat shrink oven or suitable heat source while avoiding direct flame. Heat until the tubing contracts uniformly and conforms to the underlying surface, then allow to cool to form a secure insulating layer.
Usage recommendations
Select a tube with an expanded diameter that is at most twice the largest cable diameter so that after shrinking it provides a tight fit. Use a temperature-controlled hot air gun and keep the heat source moving to prevent overheating. For outdoor use, verify material suitability for prolonged UV exposure.
