## Summary description

Single-wall heat-shrink tubing CellPack 427531 CR with nominal diameter 4.8 mm / shrunk diameter 2.4 mm (3/16") in black. Manufactured from polyolefin, it provides electrical insulation, mechanical protection and strain relief for wire joints, cable repairs and harnessing. Suitable for electronics, automotive and general electrical applications where heat activation is required.

## Long description

Heat-Shrink Tubing CellPack 427531 CR 4.8/2.4 - 3/16" black is a single-wall polyolefin sleeve designed to shrink on application of heat, providing electrical insulation, mechanical protection and strain relief for wire joints, cable repairs and harnessing. With a nominal diameter of 4.8 mm that reduces to approximately 2.4 mm after shrinking, this tubing is intended for use where compact, protected connections are required in electronics, automotive and general electrical installations.
Advantages
This polyolefin heat-shrink tubing offers consistent shrink ratio and reliable dielectric properties suitable for insulating soldered joints, splice points and exposed conductors. Its single-wall construction delivers a balance of flexibility and abrasion resistance while remaining thin enough for neat routing in confined spaces. The black colour provides uniform coverage and improved visual integration into wiring looms.
Suitable for
 Insulating and protecting solder joints and splices in electronics and control equipment
 Repairing damaged cable insulation and restoring mechanical protection
 Strain relief and bundling of wires in automotive harnesses and appliances
 Color-coded routing or identification when used with additional marking methods
When it may not be suitable
This single-wall tubing is not intended for use where chemical- or fuel-resistant jacketing is required, or where sealing against moisture ingress must be performed by an adhesive-lined product. It also is not recommended for extremely high-temperature environments beyond the polymer’s rated thermal limits or for applications requiring thick multi-layer protection.
Key specifications
 Material: polyolefin (single-wall)
 Nominal diameter before shrinking: 4.8 mm
 Approximate diameter after shrinking: 2.4 mm
 Approximate imperial size: 3/16" nominal
 Colour: black
 Primary functions: electrical insulation, mechanical protection, strain relief
How to use
Select a length of tubing slightly longer than the area to be covered, slide it over the joint or splice, then apply heat evenly using a heat gun, hot air tool or controlled flame at a safe distance. Heat until the tubing contracts smoothly and conforms to the underlying shape, then allow it to cool to room temperature before handling. For best results, ensure wires are clean and free of sharp burrs or contaminants that could compromise the insulation.
What to consider before purchase
 Confirm the pre-shrink and post-shrink diameters match the conductor, splice or connector dimensions you will cover
 Verify the material and colour suit the intended environment and visual requirements
 Assess whether a single-wall polyolefin is sufficient or if adhesive-lined or specialty tubing is needed for moisture, chemical or high-temperature protection
Usage recommendations
Use a temperature-controlled heat gun for even shrinking and to avoid overheating; test on a sample piece when working near heat-sensitive components. Trim tubing lengths to leave a small margin beyond the joint for full coverage, and allow cooling time before mechanical loading.
