Sada zmršťovacích bužírok InLine dĺžka 200 mm, priemer 9 mm → 4,5 mm, 20 kusov, čierna

Set of 20 InLine heat-shrink tubes, each 200 mm long, black, with an initial diameter of 9 mm that reduces to 4.5 mm after shrinking. These polyolefin tubes are intended for electrical insulation, cable repair and bundling. They provide mechanical protection and improved strain relief for wiring in consumer electronics, automotive and light industrial applications where a reliable insulating sleeve and tidy cable routing are required.

Advantages

The heat-shrink tube set offers uniform shrinkage and consistent wall thickness after processing, ensuring reliable insulation and protection for joints and exposed conductors. Made from polyolefin, the tubes resist abrasion, moisture and common oils, delivering improved mechanical strength around splices and connectors. The 200 mm length and stepped diameter (9 mm → 4.5 mm) give flexibility to cover larger joints and taper down to smaller cable runs without multiple pieces. Supplied in black for a discreet appearance and better light resistance in typical installation environments.

Suitable for

• Insulation of soldered or crimped electrical joints in consumer electronics
• Repairing damaged cable sheaths and restoring protective covering
• Bundling and organizing wiring looms in automotive and marine applications
• Providing strain relief at connector entries and cable transitions
• Protecting splices and sensor leads in light industrial equipment

Key specifications

• Material: polyolefin heat-shrinkable tubing
• Quantity: 20 pieces per set
• Initial outer diameter: 9 mm
• Recovered outer diameter after shrinkage: approximately 4.5 mm
• Length per piece: 200 mm
• Color: black

How to use

Slide an appropriately sized tube over the cable or joint before making the electrical connection. After soldering or crimping, position the tube to cover the splice or connector. Apply heat evenly along the tube using a heat gun or controlled flame at a safe distance until the tubing contracts and conforms to the underlying shape, ensuring complete contact and no air gaps. Allow the assembly to cool so the material hardens and forms a protective sleeve.

Recommendations

For consistent results, use a regulated hot air gun set to the manufacturer-recommended temperature for polyolefin tubing and keep the heat source moving to avoid scorching. Select a tube with sufficient length to cover the joint and provide strain relief, and choose the stepped 9 mm → 4.5 mm diameter when transitioning from larger to smaller cable bundles. Verify that the application temperature range and environmental exposure are compatible with polyolefin properties.
