InLine sada zmršťovacích bužírok 200 mm, priemer 1,5 mm → 0,75 mm, 20 ks

Set of 20 InLine heat-shrink tubes, each 200 mm long with an initial diameter of 1.5 mm that shrinks to 0.75 mm. These black polyolefin sleeves provide electrical insulation, mechanical protection and strain relief for wires, solder joints and connector bodies. The tubing is suitable for small-diameter wiring tasks in consumer electronics, automotive repairs and hobby projects where neat, reliable insulation is required.

Advantages

The polyolefin material offers reliable shrink performance and durable electrical insulation while remaining flexible after shrinking. Long 200 mm sleeves allow covering longer splices or multiple adjacent connection points in a single piece, reducing the number of separate sleeves needed. The ready-to-use length and consistent shrink ratio ensure predictable fit on thin wires and small connectors, improving repair neatness and mechanical stability.

Suitable for

• Insulating single conductors and soldered joints in consumer electronics
• Protecting and bundling small automotive wiring and sensor leads
• Repair and reinforcement of hobby electronics and model wiring
• Covering connectors and creating strain relief for thin cables

Key specifications

• Material: polyolefin heat-shrink tubing
• Quantity: 20 pieces
• Length per piece: 200 mm
• Initial outer diameter: 1.5 mm
• Final outer diameter after shrinking: 0.75 mm
• Color: black
• Shrink ratio: 2:1 (nominal)

How to use

Slide a tube over the wire or splice before making the final connection. After soldering or joining, position the sleeve to fully cover the joint and apply heat evenly along its length using a heat gun, lighter or soldering iron at a safe distance. Heat the tubing until it contracts uniformly and conforms tightly to the wire insulation and connector shapes. Allow the tubing to cool before handling to ensure a secure fit and restored insulation integrity.

Recommendations

For best results, use a controlled heat source such as a hot air gun set to moderate temperature to avoid scorching nearby components. Ensure the sleeve diameter matches the wire bundle before shrinking; the 1.5 mm starting diameter suits single conductors and small bundles that need to reach approximately 0.75 mm after shrinking. When working on automotive or critical circuits, verify insulation integrity and secure connections before returning the circuit to service.
