## Long description

CellPack heat-shrink tube model 427551 CR in black is a flexible, single-wall tubing designed to provide electrical insulation, mechanical protection and neat bundling for wires, cables and connectors. With a nominal expanded diameter of 9.5 mm and a recovered diameter of 4.7 mm (3/8" recovered), the tubing shrinks when heated to form a close-fitting sleeve that seals and protects connections in repair and assembly tasks. The black colour provides a neutral, professional appearance suitable for visible or hidden installations.
Advantages
The CellPack 427551 CR heat-shrink tube offers reliable shrink performance and consistent recovery to specified dimensions, ensuring a tight fit on irregular shapes and multi-core assemblies. Its single-wall construction gives good electrical insulation and abrasion resistance while remaining flexible for routing in confined spaces. The material adheres well to cable surfaces after heat application, improving strain relief and reducing the risk of short circuits or mechanical damage.
Suitable for
Insulating repaired wire joints and soldered connections
Protecting and bundling cable harnesses in machinery and vehicles
Covering splices and connectors in household, workshop and industrial applications
Strain relief for cables passing through panels or enclosures
Key specifications
Material: single-wall heat-shrink tubing
Colour: black
Nominal expanded diameter: 9.5 mm
Nominal recovered diameter: 4.7 mm (3/8")
Shrink ratio: designed to recover from expanded to recovered diameter when heated
Typical properties: electrical insulation, abrasion resistance and flexibility
How to use
Slide a length of heat-shrink tube over the cable or joint before making the connection, or position it over the splice once assembled. Apply heat evenly using a heat gun, hot air tool or controlled flame at an appropriate distance to avoid overheating; heat until the tubing uniformly contracts and conforms to the underlying components. Allow the tubing to cool to form a stable insulating sleeve. Trim the ends if necessary for a neat finish.
Usage recommendations
For best results, use a regulated heat gun and maintain even motion to prevent scorching. Choose tube length and wall thickness appropriate for the application, and ensure surfaces are clean and free of oils or debris before applying the tubing. Avoid direct contact with open flames on sensitive conductors or insulating materials.
