Cellpack CR Thin-Walled Heat Shrink Tubing, 4.8/2.4 mm, Yellow-Green, 1m Length, 50 Pieces

Cellpack CR thin-walled heat shrink tubing is a professional-grade solution for electrical insulation, cable identification, and mechanical protection. This set consists of 50 individual pieces, each measuring 1 meter in length, with a shrink ratio that reduces the diameter from 4.8 mm to 2.4 mm. The distinct yellow-green color is specifically standardized for marking grounding and protective earth conductors in electrical systems, ensuring safety and compliance with industry regulations.

Advantages

The tubing is manufactured from high-quality materials that offer excellent resistance to environmental factors, including moisture and chemical exposure. Its thin-walled construction allows for rapid and uniform shrinking when heat is applied, ensuring a tight, secure fit around cables and connectors. This provides robust mechanical strain relief, preventing damage to wire insulation and connections in both industrial and residential environments.

Suitable for

• Electrical insulation of wire joints and terminals
• Identification of grounding and protective earth conductors
• Mechanical protection of cables against abrasion
• Cable bundling and organization in control cabinets
• Repairing damaged cable insulation

When it may not be suitable

This tubing is not intended for use in high-temperature environments exceeding its rated thermal limits or in applications requiring heavy-duty, thick-walled protection against extreme physical impact. It should not be used for sealing pressurized systems or underwater applications where a hermetic, waterproof seal is strictly required.

Key specifications

• Shrink ratio: 2:1
• Diameter before shrinking: 4.8 mm
• Diameter after shrinking: 2.4 mm
• Color: Yellow-Green
• Length per piece: 1 meter
• Quantity: 50 pieces
• Material: Polyolefin

How to use

To use the heat shrink tubing, first cut the piece to the desired length if necessary, ensuring it is slightly longer than the area to be covered. Slide the tubing over the cable or connection point. Using a heat gun or a controlled heat source, apply heat evenly around the circumference of the tube, starting from one end and moving toward the other. Continue heating until the tubing has fully shrunk and conforms tightly to the underlying surface without any wrinkles or air gaps.

What to consider before purchase

• Verify the diameter of the cable to ensure the 4.8 mm initial size is sufficient for the application
• Confirm that the 2.4 mm final shrunk diameter provides a tight enough fit for your specific wire gauge
• Ensure the yellow-green color is appropriate for your specific identification needs
• Check if the 1-meter length is suitable for your installation requirements

Usage recommendations: Always ensure the surface of the cable is clean and free of oil or debris before applying the tubing to achieve the best adhesion and protection. Avoid overheating the material to prevent degradation or burning.
