## Summary description

Heat shrink tube bkl electronic 074120 is a black polyolefin tubing with 12.7 mm nominal diameter that shrinks to 6.4 mm (2:1 ratio). Supplied on a 50 m roll, it provides electrical insulation, strain relief and protection for wire joints, cable harnesses and connectors. Suitable for electronics repair, cable management and industrial wiring applications.

## Long description

Heat Shrink Tube bkl electronic 074120 is a black polyolefin tubing with a nominal diameter of 12.7 mm that reduces to approximately 6.4 mm when heated (shrink ratio 2:1). Supplied on a 50 m roll, this heat shrink tube is designed to provide electrical insulation, mechanical protection and strain relief for wire joints, cable splices, connectors and harnesses in electronics repair, cable management and industrial wiring contexts.
Advantages
The heat shrink material offers stable dimensional change at standard shrink temperatures and creates a tight, protective sleeve around cables and joints. Its black polyolefin composition gives good electrical insulation, abrasion resistance and basic chemical resistance, while the continuous 50 m length on a roll makes it suitable for batch work and longer runs without frequent interruptions. The 2:1 shrink ratio allows for clear sizing from larger nominal diameters down to a firm, conforming fit on smaller cables and components.
Suitable for
Insulation and protection of single wires, multi-core cables and splices
Strain relief for connector joints and cable terminations
Bundling and colour-coding where black sleeving is acceptable
Electronics repair, DIY wiring and light industrial electrical installations
When it may not be suitable
This heat shrink tube is not intended for applications requiring extremely high temperature resistance, specialized adhesive-lined sealing, or flame-retardant ratings beyond standard polyolefin performance. For situations that demand a higher shrink ratio, heat-activated adhesive lining, or certified fire resistance, a different specification of tubing should be selected.
Key specifications
Material: polyolefin (black)
Nominal diameter before shrink: 12.7 mm
Diameter after shrink: approx. 6.4 mm (2:1 shrink ratio)
Length: 50 m roll
Primary functions: electrical insulation, mechanical protection, strain relief
How to use
Measure and cut the required length of heat shrink tube to cover the joint, splice or cable section with a small overlap on each side. Slide the tubing over the area to be covered and apply heat evenly using a heat gun, hot-air tool or suitable heat source until the tubing contracts smoothly and conforms to the underlying shape. Allow the tubing to cool and verify that it forms a snug, continuous sleeve around the cable or connector.
What to consider before purchase
Required final diameter after shrink must match the cable or connector size (approx. 6.4 mm after shrink)
Material properties: polyolefin is suitable for general electrical insulation but not for high-temperature or specialized flame-retardant needs
Length and convenience of a 50 m roll versus pre-cut pieces for your workload
Usage recommendations
Use a temperature-controlled heat gun and heat evenly to avoid local overheating. For water-resistant or sealed joints, choose adhesive-lined or specially rated tubing instead of standard polyolefin. Store the roll in a cool, dry place to maintain material properties and ease of handling.
