Heat-shrink tubing CellPack CR 427615, diameter 3.2/1.6 mm (1/8"), mixed set

CellPack heat-shrink tubing model CR 427615 is a mixed set of heat-shrinkable sleeves with nominal diameters 3.2 mm and 1.6 mm (1/8"). The tubing is intended for electrical insulation, mechanical protection and strain relief of wire joints, connector terminations and exposed conductors. The compact size of the sleeves makes this set suitable for electronics assembly, repair work and cable identification where a small-diameter, durable heat-shrink solution is required.

Advantages

The CellPack CR 427615 set provides uniform wall shrinkage and reliable coverage of joints and splices, improving insulation integrity. The mixed diameters allow matching sleeve size to wire bundles and connector pins, reducing bulk while maintaining mechanical protection. The material offers good dimensional stability after shrinking and resists abrasion and moderate handling stresses.

Suitable for

• Insulating solder joints and splices in electronic circuits
• Protecting and relieving strain at connector terminations
• Repairing damaged insulation on small-diameter wires
• Cable identification and colour-coding of wire bundles

Key specifications

• Nominal diameters before shrink: 3.2 mm and 1.6 mm
• Shrink ratio suitable for reducing to smaller final diameters after heating
• Construction: heat-shrinkable sleeving for wires and connectors
• Typical applications: electrical insulation, mechanical protection, strain relief
• Compact form factor appropriate for small electronics and tight routing spaces

How to use

Select a sleeve diameter that fits over the component or wire before shrinking and centers over the joint. Slide the tubing into position, then apply even heat using a heat gun or controlled flame source at a safe distance until the tubing uniformly contracts and conforms to the underlying shape. Allow the sleeve to cool and verify that it fully covers the exposed area and provides strain relief. Trim any excess material if needed once cooled.

Usage recommendations

For consistent results, use a temperature-controlled heat gun and apply heat gradually to avoid overheating adjacent components. Choose the larger diameter sleeve for small bundles and the smaller diameter for single conductors. Inspect the shrunk sleeve for complete adhesion to the cable surface and reapply heat locally if necessary.
