Key Features of Steinel Heat Shrink Tubing

Steinel heat shrink tubing features a consistent 2:1 or 3:1 shrink ratio, depending on specification, ensuring reliable coverage across a range of cable diameters whilst maintaining sufficient wall thickness for electrical insulation. The uniform polyolefin construction provides excellent dielectric properties, making it suitable for use across low-voltage control circuits through to 240v mains applications when properly specified.

The tubing exhibits rapid and uniform shrinkage when heat is applied, eliminating the common problems of uneven contraction and localised thinning that compromise inferior products. This characteristic is particularly valuable when working with Steinel heat guns, where the precise temperature control and even heat distribution ensure optimal activation without degradation of the tubing material.

Flame-retardant formulations across Steinel's heat shrink range provide additional safety for electrical installations, with materials that resist ignition and self-extinguish when the heat source is removed. Combined with excellent resistance to common oils, fuels, and solvents, Steinel heat shrink tubing maintains its protective properties across diverse installation environments from automotive workshops to industrial plant rooms.

The smooth internal surface of Steinel heat shrink tubing allows easy cable insertion before shrinking, whilst the outer finish provides excellent adhesion once activated. Available in various colours including standard black for general applications, coloured variants enable phase identification and circuit coding in control panels and distribution systems.

Popular Steinel Heat Shrink Tubing

Tooled-Up stocks Steinel heat shrink tubing in comprehensive size ranges to accommodate cables from small electronics wiring through to substantial mains conductors. The most popular sizes include small-diameter tubing (2-6mm pre-shrink) for control circuit work and electronics repairs, medium sizes (6-12mm pre-shrink) for standard domestic cable protection, and larger diameters (12mm+ pre-shrink) for industrial cable joints and cable gland sealing applications.

Multi-pack assortments provide excellent value for electricians and contractors maintaining stock for varied site requirements, offering a selection of commonly-used sizes in convenient storage cases. Individual length cuts and continuous reels cater to both project-specific requirements and high-volume production environments where economy and waste reduction are priorities.

Specialist variants include adhesive-lined heat shrink tubing that creates a sealed, waterproof connection ideal for outdoor installations, marine applications, and underground cable joints. These advanced products feature a hot-melt adhesive inner layer that flows and seals when heated, providing superior environmental protection compared to standard heat shrink tubing.

Safety and Compliance

Steinel heat shrink tubing meets relevant European and UK safety standards for electrical insulation materials, ensuring compliance with BS 7671 wiring regulations when correctly specified and installed. Flame-retardant properties conform to international flammability standards, providing peace of mind for installations where fire safety is paramount.

Always ensure heat shrink tubing diameter and voltage rating are appropriate for the intended cable size and circuit voltage. When applying heat, maintain safe distances from flammable materials and use appropriate personal protective equipment including heat-resistant gloves when working with heat guns. Adequate ventilation should be provided when shrinking tubing, particularly in confined spaces, as heating can release minor fumes from the polymer material.

Verify that shrunken tubing completely covers exposed conductors with sufficient overlap beyond damaged insulation. The HSE recommends that all electrical repairs involving heat shrink tubing should be performed by competent persons with appropriate training, particularly for work on 240v mains circuits and industrial installations.

Frequently Asked Questions

What temperature should I use to shrink Steinel heat shrink tubing?

Steinel heat shrink tubing typically activates between 90-120°C, with complete shrinkage achieved around 120-150°C. When using Steinel heat guns, set the temperature to the lower heat setting (around 350°C air temperature) and maintain a distance of 10-15cm from the tubing, moving the heat gun continuously to ensure even shrinkage without localised overheating that could damage the material.

Can I use Steinel heat shrink tubing on 240v mains cables?

Yes, Steinel heat shrink tubing is suitable for 240v mains applications when correctly sized and installed, providing adequate electrical insulation properties. However, ensure you select tubing with appropriate voltage rating and wall thickness for mains work, and verify that all conductors are fully covered with no exposed copper visible after shrinking. Any mains electrical work must comply with Part P Building Regulations and BS 7671 wiring standards.

How do I choose the right size heat shrink tubing?

Measure the diameter of the cable or component requiring coverage, then select heat shrink tubing with a pre-shrink (supplied) diameter approximately 20-30% larger than this measurement. For 2:1 shrink ratio tubing, the shrunken diameter will be half the supplied diameter, so a 10mm tube shrinks to 5mm. Ensure the shrunken diameter will grip the cable firmly whilst the pre-shrink diameter allows easy installation over cables and any inline components.

What's the difference between standard and adhesive-lined heat shrink tubing?

Standard heat shrink tubing provides mechanical protection and electrical insulation but remains porous to moisture over time. Adhesive-lined (also called dual-wall) heat shrink tubing features an internal hot-melt adhesive layer that flows when heated, creating a waterproof seal around the cable. This makes adhesive-lined tubing essential for outdoor installations, underground joints, marine applications, and any environment where moisture ingress could compromise electrical integrity.

How long does Steinel heat shrink tubing remain stable once installed?

When correctly installed, Steinel heat shrink tubing provides long-term protection, typically maintaining its properties for 10-20 years or more depending on environmental conditions. The polyolefin material resists UV degradation, temperature cycling, and chemical exposure significantly better than PVC alternatives. For maximum longevity, ensure tubing is not over-heated during installation, is fully shrunk with no air gaps, and provides complete coverage of the protected area with adequate overlap beyond damaged insulation.
