Θερμοσυστελλόμενο μακαρόνι Cimco 181680 Μαύρο 1,25 cm Διάμετρος

Cimco 181680 Black 1.25 cm diameter heat shrink tubing is a flexible polymer sleeve designed to provide electrical insulation and mechanical protection for wires and cable joints. Sized at 1.25 cm diameter before shrinking, the tubing reduces in diameter when heated, forming a tight, protective layer that resists abrasion, moisture and moderate chemical exposure. The black color offers a neutral finish suitable for visible installations and general-purpose wiring tasks.

Advantages

This heat shrink tubing creates a uniform, conforming cover that improves the durability and safety of electrical connections. Its shrink-on application ensures a snug fit over connectors, splices and cable transitions, reducing movement and exposure. The material provides electrical insulation, strain relief and basic protection against dust and light moisture, while the black finish conceals joins for a neat appearance.

Key specifications

• Colour: black
• Nominal diameter before shrinking: 12.5 mm
• Material type: heat-shrinkable polymer
• Shrink mechanism: thermal (requires heat source for shrinking)
• Primary functions: electrical insulation, mechanical protection, strain relief
• Typical shrink ratio: standard single-wall shrink (ratio depends on material)

How to use

Slide the tubing over the wire, splice or connector so that it fully covers the area to be insulated. Apply heat evenly along the length of the tubing using a heat gun, hot air tool or suitable heat source until the tubing contracts and conforms tightly around the underlying components. Allow the tubing to cool so it sets firmly in place before handling. Ensure the heat source is kept at a safe distance and moved continuously to avoid overheating the conductor or insulation.

Recommendations

For consistent results, use a regulated hot air gun and maintain even motion to achieve uniform shrinkage. Select tubing with appropriate pre-shrink diameter and wall thickness for the cable bundle to ensure full coverage and proper strain relief. Avoid open flames and excessive localized heat. Use in environments and on components within the thermal and chemical resistance limits of standard heat-shrinkable polymer tubing.
