RESISTANT SILICONE WIRE COIL - Avoid the risk of short circuits. The silicone jacket is resistant to extreme temperatures. Your line will not freeze at temperatures above -76°F and will not melt with overheating below 392°F. 12AWG PURE COPPER CONDUCTOR - Guaranteed the quality of the electrical connections. In this case, the 658 strands 99.9% Oxygen Free-Copper wire has a higher electrical conductivity and lower resistivity than copper-clad aluminum wire. TOUGH AND FLEXIBLE - Rated up to 600V and can be used for many application such as automotive, lighting, model car, robotic, computer power supply, drone, or 3D printer. EASY SOLDERING TIN COATED - Save time and increases the effectiveness of electrical connections. This soft and flexible wire conductor is coated with a tin layer that facilitates the joining of the wires by soldering. AVAILABLE IN SEVERAL SIZES - Each GearIT electric silicone wire is available in different sizes to suit your needs, from 16 AWG gauge to 12 AWG and, lengths ranging from 25 to 100 feet.
