Heat shrink tubing Radpol RCH1 WRJCC1600080010030C1 1.6/0.8×1 black

Radpol RCH1 heat shrink tubing WRJCC1600080010030C1 is a black, single-wall thermoplastic sleeve with nominal dimensions 1.6/0.8×1. It is designed to insulate and protect wires, soldered joints and cable terminations by providing a snug, heat-activated covering that reduces exposure to mechanical abrasion and environmental contaminants. The tubing shrinks reliably when heated to form a tight fit around conductors and splices, offering a professional finish for wiring repairs and installations.

Advantages

The tubing provides electrical insulation and mechanical protection in a compact, easy-to-apply form factor. Its controlled shrink ratio ensures consistent coverage of joints and terminations, while the black colour offers discreet appearance and UV resistance appropriate for many indoor and outdoor wiring applications. The material resists moisture and common contaminants, helping to extend the service life of connections and reduce the risk of short circuits.

Suitable for

• Insulating single conductors and multi-core cable joints
• Repairing damaged cable insulation and protecting soldered connections
• Providing strain relief at cable terminations and connector interfaces
• Organizing and marking wiring runs in electronics and control panels

Key specifications

• Colour: black
• Nominal dimensions: 1.6/0.8×1 (inner diameter before shrink/after shrink × length)
• Material type: single-wall thermoplastic shrink tubing
• Shrink ratio: designed for reliable reduction to specified post-shrink diameter
• Primary functions: electrical insulation, mechanical protection, environmental sealing

How to use

Cut the tubing to the required length and slide it over the conductor, joint or connector prior to making the connection when possible. Apply heat evenly using a heat gun, hot-air tool or suitable soldering iron accessory, moving the heat source along the tubing to ensure uniform shrinkage. Continue heating until the tubing conforms tightly to the underlying parts and any folds or air pockets are removed. Allow the assembly to cool before handling.

Usage recommendations

For best results, select tubing slightly larger than the part to be covered before shrinkage to allow adequate coverage, and apply heat in controlled passes to avoid overheating. Verify compatibility with the application temperature range and electrical requirements; avoid direct flame contact and use proper personal protective equipment when heating.
