500-Piece Solder Seal Wire Joint Kit, Transparent Heat Shrink Butt Joints, Waterproof Electrical Cable Repair Set, 3:1 Shrink Ratio, No Crimping Need

500-Piece Solder Seal Wire Joint Kit, Transparent Heat Shrink Butt Joints, Waterproof Electrical Cable Repair Set, 3:1 Shrink Ratio, No Crimping Needed, for Automotive, Marine, Boat, Home Wiring Complete 500-Piece Assortment: Includes 160 solder seal wire joints (40 white, 50 red, 50 blue, 20 yellow) and 340 black heat shrink tubes (φ3mm, 20mm length). A generous supply for automotive, marine, home wiring, and outdoor cable repair projects. Waterproof & Secure Seal: Each joint contains a low-temperature solder ring and two hot melt adhesive bands. When heated, they melt and flow to create a 3:1 shrink ratio, fully sealed, waterproof connection that prevents moisture and oxidation. No Crimping, No Soldering Iron: Simply insert the wires and apply heat evenly with a 1500-2000W heat gun (not included). The solder melts and the tubing shrinks simultaneously to form a strong, lasting bond in seconds, saving time and effort. Transparent Inspection Design: The clear heat shrink tubing allows you to visually verify the solder flow and wire connection, ensuring a reliable joint every time. Wide Application: Ideal for electronics, railways, ships, automobiles, motorcycles, aerospace, and other industrial or outdoor wiring tasks. Compatible with a broad range of wire gauges.
