Heat shrink tubing Radpol WRJCC9500480010030J1 RCH1 9.5/4.8 yellow

Radpol heat shrink tubing WRJCC9500480010030J1 RCH1 in yellow is a polymer sleeve designed to reduce its diameter when heated, forming a tight, insulating layer around wires, cable joints and connectors. With nominal expanded diameter 9.5 mm and recovered diameter 4.8 mm, this tube provides predictable recovery for electrical insulation, mechanical protection and strain relief in repair and installation tasks. The material is suitable for creating sealed terminations and tidy cable bundles after heat application.

Advantages

This yellow heat shrink tubing offers reliable dimensional recovery and consistent insulating properties after shrinking, ensuring stable electrical isolation of conductors. Its visible color simplifies identification of repaired or insulated sections and helps during installation and maintenance. The tubing delivers mechanical protection against abrasion and light impact, while conforming tightly to irregular shapes for improved sealing and reduced moisture ingress when properly applied with heat.

Suitable for

• Insulating single conductors and small cable joints
• Sealing crimped or soldered connectors
• Providing strain relief on cable exits and connector interfaces
• Bundling and colour-coding wire groups in installations

Key specifications

• Colour: yellow
• Nominal expanded diameter: 9.5 mm
• Nominal recovered diameter: 4.8 mm
• Material: heat-shrinkable polymer (polyolefin-type performance)
• Recovery ratio: engineered to achieve specified recovered size upon heating
• Primary functions: electrical insulation, mechanical protection, strain relief

How to use

Select a length of tubing appropriate to cover the joint or connector with additional overlap. Slide the tubing over the area to be insulated before making the final connection, or position it over the joint and then apply heat evenly along its length using a heat gun or other controlled heat source. Heat until the tubing uniformly contracts and conforms tightly to the substrate; avoid direct open flames and excessive local overheating. Allow the tubing to cool and set before handling.

Usage recommendations

For best results, use a regulated hot-air gun with even temperature distribution and move the heat source continuously to prevent scorching. Ensure surfaces are clean and free of oils or contaminants before shrinking. For environmental sealing or enhanced moisture resistance, combine the tubing with appropriate adhesive-lined variants or additional sealing methods where required by the application.
