The Heat Shrink Sleeves 1 Meter (2/3/4/5/6/8/10mm) are flexible insulating tubes designed to provide electrical insulation, wire protection, cable bundling, and strain relief for electronic and electrical connections. When heated with a suitable heat source, the sleeve shrinks tightly around the wire, terminal, solder joint, or connector to create a secure and neat protective covering.
Available in multiple diameters, including 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, and 10mm, these heat shrink sleeves are suitable for a wide range of wire sizes and electronic applications. The 1-meter length makes them convenient for cutting into smaller sections according to project requirements.
They are an essential accessory for electronics assembly, soldering, robotics, automotive wiring, DIY projects, PCB work, and general electrical repairs.

Working Principle
Heat shrink tubing is placed over a wire, cable, terminal, or electrical connection before the connection is completed or before the end is inaccessible.
After positioning the sleeve, controlled heat is applied using a heat gun or other suitable heat source. The tubing contracts around the connection, creating a tight protective layer.
The resulting covering helps:
- Insulate exposed conductors
- Protect solder joints
- Reduce the possibility of accidental short circuits
- Provide mechanical protection
- Improve cable organization
- Provide strain relief around suitable connections
Different sleeve diameters can be selected depending on the size of the wire or connection being covered.
Size Selection Guide
- 2mm: Suitable for very thin wires and small electronic connections
- 3mm: Suitable for small-gauge wires and compact connections
- 4mm: Suitable for small to medium wires and terminals
- 5mm: Suitable for medium-sized wire connections
- 6mm: Suitable for larger wires and connector sections
- 8mm: Suitable for thicker wires and cable bundles
- 10mm: Suitable for larger cables, terminals, and bundled wires
Note: Select a sleeve that can slide over the connection before heating but will shrink tightly around the wire or joint after heating.

Usage Tips
- Select the appropriate diameter according to the wire and connection size.
- Slide the sleeve onto the wire before soldering if the completed connection is too large for the sleeve to pass over.
- Center the sleeve over the exposed connection before applying heat.
- Use a heat gun for controlled and even heating.
- Apply heat gradually rather than holding excessive heat in one location.
- Avoid overheating the sleeve or surrounding components.
- Allow the sleeve to cool before moving the connection.
- Make sure the sleeve has sufficient overlap on both sides of the exposed area for proper insulation.
- Do not rely on heat shrink tubing as the sole protection against high mechanical loads or environments beyond its specifications.
