Sourcingmap Polyolefin Heat Shrink Tubing - 50mm Diameter, 2:1 Shrink Ratio, Clear, 1 Meter (3.3 Ft) Long

Got wires, cables, or connections that need protecting, insulating, or bundling together? This heat shrink tubing is an incredibly useful material to have in your DIY, electronics, or repair toolkit. This specific piece is a clear polyolefin tube that's 50mm (almost 2 inches) in diameter before you shrink it, and it comes in a 1-meter (3.3-foot) length. The '2:1 shrink ratio' means when you apply heat, it'll shrink down to about half its original diameter – so roughly 25mm or 1 inch. You simply slide it over the item you want to protect (like a spliced wire connection, the end of a cable, or even a metal rod to prevent corrosion), then gently warm it up with a heat gun, hairdryer, or carefully with a lighter. As it heats, it shrinks tightly to form a snug, protective skin. It's rated for 600 volts and can handle temperatures up to 125°C, and it meets the VW-1 flammability standard. The clear color lets you see what's underneath, which is great for inspections. Use it to insulate electrical connections, waterproof wire splices, bundle cables into a neat harness, protect antenna elements, or even reinforce the ends of ropes. It's a fast, clean, and professional-looking solution for all sorts of odd jobs.
