127 Pcs Black Heat Shrink Tubing Kit 2:1 Shrink Ratio

The 127 Pcs Black Heat Shrink Tubing Kit is an essential wire management and insulation solution designed for electronics hobbyists, makers, students, and professional engineers in India. Made from high-quality polyolefin, these flame-retardant sleeves feature a 2:1 shrink ratio, allowing them to shrink to half of their original diameter when heat is applied. This ensures a tight, secure, and highly protective seal over solder joints, wire splices, terminals, and component connections.

This versatile assortment is highly compatible with various DIY electronics, robotics, IoT prototyping, RC vehicles, and household electrical repair projects. Whether you are insulating delicate sensor wires on an Arduino build or bundling cables for a custom 3D printer, this kit provides a neat, professional, and reliable finish. The tubes can be easily activated using a standard heat gun, soldering iron barrel, or lighter, making them incredibly convenient for both lab environments and field repairs.

Features:

• 2:1 Shrink Ratio: Shrinks to exactly half of its pre-shrunk diameter to provide a snug, form-fitting protective layer.
• Flame Retardant Polyolefin: High-grade material offers excellent electrical insulation, mechanical toughness, and self-extinguishing safety properties.
• 7 Popular Sizes: Includes a comprehensive range of diameters from 2.0mm up to 13.0mm to accommodate various wire gauges and cable thicknesses.
• Wide Temperature Range: Operates reliably in harsh environments with a working temperature range of -55°C to +125°C.
• Low Shrinkage Temperature: Begins shrinking at just +70°C and achieves full recovery at +110°C for quick and easy application.
• Professional Black Finish: Delivers a clean, uniform look to custom cable harnesses and exposed wiring.
