Our 18 gauge wire is part of our Hook Up Wire / Lead Wire line. An 18 AWG wire with a silver-plated copper conductor with a 19/30 stranding, PTFE insulation, and a nominal outside diameter of 0.069. Weighing approximately 8 lbs/MFT, this wire is easy to install due to its small size and slippery surface. These cables are generally used in high-temperature electronic applications and are ideal for high-frequency applications due to their low power loss. As a result of this, these cables are also military rated with a Mil-Spec number of M16878/4BHE
