Heat-Shrink Tube Cabletech LEC-NAR0252.1 1.5 mm × 1 m, red, shrinkable insulation tubing

Cabletech heat-shrink tube LEC-NAR0252.1 is a red, shrinkable insulation sleeve with an initial diameter of 1.5 mm and a length of 1 m. It is intended to provide electrical insulation and mechanical protection for wire joints, terminals and small cable sections. The tubing is suitable for repair and finishing tasks in electronics, automotive wiring and general electrical maintenance where a colored, narrow-diameter sleeve is needed.

Advantages

The heat-shrink tube offers reliable dielectric insulation and improved strain relief for soldered or crimped connections. Its red color allows quick identification of circuits or polarity. The product’s narrow diameter and flexible material make it easy to position over small gauge wires and terminals before heat application. After shrinking, the sleeve conforms to irregular shapes and provides abrasion resistance and reduced exposure to moisture and contaminants.

Suitable for

• Insulating and protecting spliced wires and solder joints
• Color-coding wires and connectors in small electrical assemblies
• Repairing damaged insulation on low-voltage cables
• Providing strain relief at terminals and connector ends

Key specifications

• Material: heat-shrinkable polyolefin (typical for this type of tubing)
• Initial diameter: 1.5 mm
• Length: 1 m
• Color: red
• Shrink ratio: standard low-voltage shrinkage suitable for small wires

How to use

Slide the heat-shrink tube over the connection or area to be protected before making the joint, or position it over the joint after assembly if access permits. Apply heat evenly using a heat gun, hot-air tool, or controlled flame at a safe distance until the tube contracts and conforms to the underlying conductor or connector. Allow the sleeve to cool and check that it is snug and free of gaps. Trim excess length as needed for a neat finish.

Usage recommendations

Use appropriate heat equipment at the recommended distance and temperature to avoid damage to nearby components or insulation. For electrical applications, ensure wires are de-energized before installation and verify adequate clearance and insulation for the intended voltage. Select tube diameter and length to allow overlap on both sides of the joint for secure coverage.
