Θερμοσυστελλόμενο μακαρόνι InLine 200 mm, 3 mm → 1,5 mm, 20 τεμ., μαύρο

InLine heat-shrink tubing set contains 20 black tubes, each 200 mm long, with a nominal shrink ratio from 3 mm to 1.5 mm. Made from flexible polyolefin material, the tubing is intended to insulate and protect wire joints, soldered connections and cable ends. The design provides reliable electrical insulation and mechanical protection for small-diameter wiring runs in electronics, automotive harnesses and general repair tasks.

Advantages

The polyolefin construction offers good flexibility, electrical insulation and resistance to abrasion. Long 200 mm lengths allow cutting to size for a range of applications, while the nominal shrinkage from 3 mm to 1.5 mm ensures a tight fit around single conductors and small connectors after heat application. Packaged as 20 pieces in black, the set provides consistent appearance and multiple replacements for maintenance or hobby projects.

Suitable for

• Insulating solder joints and splices on low-voltage wiring
• Protecting exposed cable ends and stranded conductors
• Automotive wiring repairs and harness maintenance
• DIY electronics, prototyping and hobby projects
• Bundling and identifying small wire runs

Key specifications

• Material: polyolefin heat-shrink tubing
• Colour: black
• Quantity: 20 pieces per set
• Individual tube length: 200 mm
• Nominal diameter before shrink: 3 mm
• Nominal diameter after shrink: 1.5 mm
• Shrink ratio: designed to reduce diameter approximately by 50%

How to use

Select a tube of suitable length and slide it over the wire or connector before completing the solder joint or splice. Apply heat evenly along the tubing using a heat gun, hot-air tool or lighter at a safe distance until the tubing contracts and forms a snug seal around the conductor. Allow the tubing to cool to room temperature before handling; cut to length first if required and avoid direct flame contact for prolonged periods to prevent damaging the material.

Recommendations

For best results, use a temperature-controlled heat gun set to the manufacturer-recommended temperature range for polyolefin (typically 120–200 °C). Pre-test on a spare piece to confirm shrink behaviour and avoid overheating nearby components. When working on automotive or outdoor applications, combine tubing with adhesive-lined variants only where additional moisture protection is required.
