Heat Shrink Tube Set ORNO OR-AE-13141 — multicolour tubing assortment for insulation and cable repair

ORNO OR-AE-13141 is a multicolour heat shrink tube set intended for electrical insulation, cable protection and small repair tasks. The assortment contains different diameters and lengths of coloured shrink tubing that contract when heated to form a tight, protective sleeve around wire joints, terminals and exposed conductor sections. The product is suitable for use in household wiring, electronics assembly, automotive repairs and other situations where compact, reliable insulation and strain relief are required.

Advantages

The heat shrink tube set provides a colour-coded solution for identifying and organising wiring while offering moisture and abrasion resistance after shrinking. Tubing material creates a durable insulating layer that helps prevent short circuits and improves mechanical stability of soldered or crimped connections. The variety of sizes in the assortment reduces the need to cut custom lengths and allows matching tubing diameter to wire gauge for an effective fit.

Suitable for

• Insulating wire splices and solder joints
• Providing strain relief on cable ends and connectors
• Colour-coding wiring in panels, electronics and automotive systems
• Repairing damaged insulation on household appliances and tools

Key specifications

• Material: polyolefin heat-shrink tubing (typical for this product type)
• Colour: multicolour assortment for identification
• Shrink ratio: standard heat-shrink behaviour to form a tight fit on wires (approx. 2:1 typical for similar tubing)
• Application range: electrical insulation, cable protection, strain relief and minor repairs

How to use

Select a tube from the ORNO set that matches the wire diameter before shrinking. Slide the tube over the wire joint or connection so it fully covers the exposed area. Apply heat evenly using a heat gun, lighter or other controlled heat source until the tubing contracts and conforms to the wire, ensuring full coverage and a secure mechanical fit. Allow the tubing to cool before handling and verify that insulation and strain relief are satisfactory.

Usage recommendations

When applying heat, maintain a safe distance and use a heat gun at recommended settings to avoid damaging insulation or nearby components. For higher-voltage applications or where environmental resistance is critical, choose tubing with appropriate specifications and follow local electrical safety standards.
