Cellpack CR Thin-Walled Heat Shrink Tubing 25.4/12.7 mm Black 1m

The Cellpack CR thin-walled heat shrink tubing is a high-quality solution for electrical insulation and cable management. With an initial diameter of 25.4 mm and a shrink ratio of 2:1, this tubing effectively reduces to 12.7 mm when heated, ensuring a tight and secure fit around cables, wires, and connectors. Its durable construction provides excellent mechanical protection and reliable insulation for various electrical installations.

Advantages

This heat shrink tubing offers exceptional versatility and ease of use in both professional and DIY environments. The material is designed to withstand standard environmental stresses, providing a robust barrier against abrasion and moisture. Its consistent shrink performance ensures that cable joints and terminations remain protected, while the black finish provides a clean, professional appearance for any wiring project.

Suitable for

• Electrical insulation of wires and cables
• Protection of cable joints and terminations
• Bundling and organizing electrical wiring
• Strain relief for cable connections
• Identification and marking of cable runs

When it may not be suitable

This product is not intended for use in high-temperature environments exceeding its thermal rating or in applications requiring heavy-duty chemical resistance. It should not be used as a primary structural support for heavy cables or in areas exposed to continuous high-pressure fluid contact.

Key specifications

• Shrink ratio: 2:1
• Initial diameter: 25.4 mm
• Shrunk diameter: 12.7 mm
• Material: Thin-walled polyolefin
• Color: Black
• Length: 1 meter

How to use

To use the Cellpack CR heat shrink tubing, first cut the required length from the 1-meter piece. Slide the tubing over the cable or joint you wish to protect. Apply heat evenly around the circumference of the tube using a heat gun or a similar controlled heat source. Start from one end and move toward the other to prevent air bubbles. The tubing will shrink rapidly to conform to the shape of the underlying object, creating a secure and insulated seal once cooled.

What to consider before purchase

• Ensure the initial diameter is large enough to slide over your specific cable or connector.
• Verify that the shrunk diameter provides a tight fit for the intended application.
• Check the environmental conditions of your project to ensure compatibility with standard polyolefin tubing.

Usage recommendations

For the best results, always ensure the surface of the cable is clean and free of oils or debris before applying the tubing. Use a heat gun with a temperature-controlled nozzle to avoid overheating or damaging the material.
