White x 50: 1.5mm diameter, 0.25-0.34mm² cable section (A.W.G: 26-24); Red x 130: 3.0mm diameter, 0.5-1.0mm² cable section (A.W.G: 22-18); Blue x 100: 5.0mm diameter, 1.5-2.5mm² cable section (A.W.G: 16-14); Yellow x20: 6.0mm diameter, 4.0-6.0mm² cable section (A.W.G: 12-10); [PREMIUM SOLDER SEAL RING] The tubing shrinks to melt sufficient solder, which flows through stripped wires to ensure a long-lasting connection for your applications. [BETTER WATERPROOF SOLUTIONS] Double-wall design with hot melt adhesive inside secures wires tightly to prevent slipping, while the outer polyolefin tubing provides insulation and enhances pullout strength. [ABRASION RESISTANCE HEAT SHRINKABLE TUBE] Crafted from premium materials, the tube is designed for harsh environments, protecting wires and cables from abrasion, cutting, scuffing, and low-impact damage. [WIDE APPLICATIONS] With excellent stability, water resistance, and electrical conductivity, it offers durable connections for motorcycles, off-road vehicles, lawn tractors, RVs, fish finders, and marine applications. Widely used in Christmas lights, high-waterproof ships, motorcycle stereos, boat electronics, and equipment switches. [EXCELLENT WIRE CONTACT] The tin barrel enhances current flow, minimizes voltage drop, prevents wiring failures, and reduces equipment downtime.
