Zmršťovacia bužírka InLine dĺžka 200 mm, 6 mm na 3 mm priemer, 20 ks, čierna

Heat shrink tubing InLine 200 mm length, 6 mm to 3 mm diameter, 20 pcs, black is a set of 20 identical black heat-shrinkable sleeves, each 200 mm long and engineered to reduce from 6 mm outer diameter to 3 mm after heat application. These tubes provide insulating protection, mechanical reinforcement and environmental sealing for splices, solder joints and exposed conductor sections. The consistent shrink ratio and uniform length make the set suitable for repeatable repairs and installations in electronics, automotive wiring and general household electrical tasks where a controlled reduction in diameter is required.

Advantages

The tubing offers reliable electrical insulation and abrasion resistance while maintaining flexibility after shrinking. Its predictable shrink ratio ensures a close fit on repaired joints and cables, improving strain relief and reducing the risk of short circuits. Supplied in a pack of 20, the sleeves allow multiple repairs or installations without frequent restocking, and the 200 mm length supports longer coverage and overlap on connectors or combined multi-core sections.

Suitable for

• Insulating and protecting wire splices and solder joints
• Cable repair and reinforcement in automotive and motorcycle wiring
• Sealing and strain relief for connectors and terminal blocks
• Electronics projects and prototyping where diameter reduction is needed
• Household electrical maintenance and appliance wiring repairs

Key specifications

• Material: heat-shrinkable polymer
• Initial outer diameter: 6 mm
• Final outer diameter after shrink: approximately 3 mm
• Length per piece: 200 mm
• Quantity: 20 pieces
• Color: black
• Shrink ratio: 2:1

How to use

Slide a sleeve over the wire or component before making the splice or solder joint. After joining conductors and allowing any solder to cool, position the tubing so it fully covers the exposed area and any overlap needed for strain relief. Apply heat evenly using a heat gun, hot-air station or a regulated flame source at a safe distance, moving the heat source along the tubing until it conforms tightly to the underlying cable. Allow the tubing to cool to room temperature before handling to ensure a stable seal and insulation.

Recommendations

For best results use a controlled heat gun set to the manufacturer's recommended temperature range for polyolefin tubing. Avoid direct prolonged flame contact that can cause uneven shrinking or damage to insulation. Choose the 6→3 mm tubing where the pre-shrink diameter accommodates the components or bundled conductors; for larger bundles select a different size with an appropriate shrink ratio.
