Cellpack CR Thin-Walled Heat Shrink Tubing 38.1/19.1 mm, 1.5 inch, Blue, 1m

The Cellpack CR thin-walled heat shrink tubing is a high-quality solution for electrical insulation, cable protection, and identification. Engineered for professional use, this tubing offers a reliable way to secure connections and protect cables from mechanical stress and environmental factors. With a shrink ratio of 2:1, it ensures a tight and uniform fit around wires and connectors, providing long-lasting durability in various electrical applications.

Advantages

This heat shrink tubing is characterized by its excellent flexibility and high mechanical strength, making it ideal for demanding electrical installations. The material is resistant to common environmental influences, ensuring that your connections remain protected over time. Its precise shrink ratio allows for easy application, while the vibrant blue color facilitates clear identification of cables within complex wiring systems. The thin-walled design maintains a low profile, which is essential for installations where space is limited.

Suitable for

• Electrical insulation of wires and cable joints
• Mechanical protection of connectors and terminals
• Color-coding and identification of electrical circuits
• General repair and maintenance of electrical systems

When it may not be suitable

This tubing is not intended for high-temperature environments that exceed the material's thermal rating or for applications requiring heavy-duty abrasion resistance beyond standard electrical protection. It should not be used for sealing pressurized systems or in environments with aggressive chemical exposure.

Key specifications

• Shrink ratio: 2:1
• Diameter before shrinking: 38.1 mm
• Diameter after shrinking: 19.1 mm
• Color: Blue
• Length: 1 meter
• Wall type: Thin-walled

How to use

To apply the tubing, first cut the required length to cover the area needing protection. Slide the tubing over the cable or connector before making the connection. Once positioned, apply heat evenly using a heat gun or a suitable heating tool, moving from one end to the other to prevent air bubbles. The tubing will shrink rapidly to conform to the shape of the underlying component. Allow the material to cool completely before handling the connection to ensure a secure and stable fit.

What to consider before purchase

• Ensure the diameter before shrinking is large enough to slide over your specific connector or cable assembly.
• Verify that the final shrunk diameter provides a tight fit for your specific wire gauge.
• Confirm that the blue color meets your specific identification or aesthetic requirements.

Usage recommendations: Always use a heat gun with a temperature-controlled nozzle to ensure even heat distribution and prevent overheating or scorching the material. Avoid using open flames, as they can cause uneven shrinking and damage the integrity of the tubing.
