## Summary description

CellPack heat shrink tube model 427501 (CR) is a black single-wall sleeve with nominal dimensions 1.6 mm expanded and 0.8 mm recovered (1/16" recovered). Designed for electrical insulation, wire bundling and protection against abrasion and moisture. Suitable for cable repair, joint insulation, strain relief and general wiring applications in electronics and automotive contexts.

## Long description

CellPack heat shrink tube model 427501 CR is a single-wall, black polyolefin sleeve with nominal expanded diameter 1.6 mm and recovered diameter 0.8 mm (1/16"). It is designed for electrical insulation, mechanical protection and light sealing of wires and small cable assemblies. The tube provides a smooth, conformal covering that restores insulation after repairs and improves resistance to abrasion and incidental moisture contact in electronics and automotive wiring.
Advantages
This single-wall heat shrink tube offers predictable shrink ratio and stable recovered diameter, enabling precise insulation on small-diameter wires and component leads. The black polyolefin material resists wear and provides dielectric separation between conductors while remaining flexible after shrinkage. Its nominal dimensions (1.6 mm expanded to 0.8 mm recovered) make it suitable for neat, compact applications and for restoring protective sleeving after splicing or soldering.
Suitable for
Insulation of wire joints and soldered connections
Strain relief on small cables and component leads
Bundling and identifying wiring in compact assemblies
Minor abrasion and moisture protection in electronics and automotive systems
Key specifications
Material: single-wall polyolefin
Colour: black
Nominal expanded diameter: 1.6 mm
Nominal recovered diameter: 0.8 mm (1/16")
Function: electrical insulation, mechanical protection
Form factor: tubular sleeve for heat shrinking
How to use
Select the appropriate length of heat shrink tube to cover the connection or section of cable requiring protection. Slide the sleeve over the joint or area to be insulated before completing the splice or soldering; if applying after a repair, position the tube over the finished connection. Apply heat evenly using a heat gun or other suitable controlled heat source until the tube contracts and conforms to the underlying substrate. Allow the sleeve to cool so it forms a stable insulating layer.
Usage recommendations
For reliable results, use a temperature-controlled heat gun and apply heat gradually to avoid overheating surrounding components. Ensure the underlying surfaces are free of contaminants and sharp edges that could compromise insulation. Choose the correct recovered diameter to achieve snug coverage without excessive stretching.
