Heat-Shrink Tubing Shumee CR thin-wall 12.7/6.4 mm (1/2") yellow-green, 1 m, pack of 50

Thin-wall heat-shrink tubing Shumee CR with 12.7 mm expanded and 6.4 mm recovered diameter (1/2") in yellow-green, 1 m length per piece, supplied as a pack of 50. The tubing is intended for electrical insulation, cable bundling, strain relief and colour-coding of wires and connectors in electronics, automotive and industrial applications. Its thin-wall construction provides a compact recovery profile while maintaining flexibility and reliable coverage for small- and medium-diameter cables.

Advantages

This Shumee CR thin-wall heat-shrink tubing offers consistent shrink ratio and dimensional stability after heating, enabling precise fitting on wires and connectors. The yellow-green colour supports visual identification and colour-coding of circuits or harnesses. Delivered in 1 m lengths and a pack of 50, the product is suited for repeated installations and projects that require uniform pieces. The material provides electrical insulation and mechanical protection without adding significant bulk.

Suitable for

• Insulating splices and solder joints in electronics and electrical assemblies
• Cable bundling and harness organisation in automotive and industrial equipment
• Colour-coding wires and connectors for circuit identification
• Providing strain relief at connector entries and transition points

Key specifications

• Expanded diameter: 12.7 mm
• Recovered diameter: 6.4 mm
• Nominal recovered diameter ratio: 2:1
• Wall type: thin-wall
• Colour: yellow-green
• Length per piece: 1 m
• Pack quantity: 50 pieces

How to use

Measure and cut the tubing to the required length so that it covers the exposed section of wire or the splice with some overlap. Slide the tubing over the cable or joint before making the connection where possible; for retrofitting, position it over the assembled connector. Apply heat evenly using a heat gun or calibrated hot air tool, moving the heat source along the length to ensure uniform shrinkage until the tubing conforms tightly to the substrate and the intended recovered diameter is reached. Allow the tubing to cool and set before handling.

Usage recommendations

Use a temperature-controlled heat gun and maintain appropriate working distance to prevent overheating. For applications requiring enhanced mechanical protection or environmental sealing, consider using adhesive-lined or thicker-wall variants. Store the tubing in a cool, dry place away from direct sunlight to preserve material properties.
