## Summary description

Radpol RCH1 heat-shrink tube, model WRJCC6400320010030C1, in black. Nominal dimensions 6.4 mm outer, 3.2 mm inner before shrinking, with 1 mm wall (as indicated). Designed for electrical insulation, cable repair and strain relief on wires and connectors. Provides mechanical protection and moisture resistance in wiring harnesses, junctions and electronic assemblies.

## Long description

Radpol RCH1 heat-shrink tube WRJCC6400320010030C1 in black is a polyolefin insulation sleeve designed for electrical insulation, cable repair and strain relief. With nominal pre-shrink dimensions of 6.4 mm outer diameter, 3.2 mm inner diameter and a 1 mm wall thickness, the tube provides mechanical protection and improved moisture resistance for wiring harnesses, junctions and electronic assemblies. The product is compatible with common heat sources used for shrink tubing and is intended for use where standardized shrink ratios and consistent wall integrity are required.
Advantages
The heat-shrink tube offers uniform shrinkage and stable dielectric properties after processing, delivering reliable insulation and mechanical reinforcement. Its 1 mm wall thickness ensures a robust protective layer over repaired conductors and connector joints, while the polyolefin material balances flexibility with abrasion resistance. The black coloration provides UV masking and a neutral appearance for wiring applications.
Suitable for
Electrical insulation of single conductors and splices
Repairing damaged cable jackets and restoring mechanical protection
Strain relief at connector terminations and solder joints
Bundling and organizing wiring in control panels and harnesses
Protection against moisture and light mechanical abrasion in electronic assemblies
Key specifications
Material type: polyolefin heat-shrink
Pre-shrink outer diameter: 6.4 mm
Pre-shrink inner diameter: 3.2 mm
Wall thickness (nominal): 1 mm
Color: black
Shrink ratio: standard ratio suitable for reducing to fit smaller diameters (as typical for RCH1 series)
How to use
Select a length of tube that covers the damaged area or splice with sufficient overlap onto the intact insulation. Slide the tube into position before making the final connection or apply it over the repair. Heat uniformly using a heat gun, hot-air station or equivalent heat source, maintaining a safe distance and moving the heat source to avoid local overheating. Allow the tube to cool so it forms a tight, conformal layer around the conductor or connector. Inspect the finished joint for complete adhesion and shrinkage.
Usage recommendations
For best results, use a regulated heat gun and monitor applied temperature to avoid overheating. Ensure surfaces are clean and free of oils or contaminants before application. When used in environments with potential UV exposure, verify long-term suitability as required by the installation.
