Arctic Ultraflex Blue® pairs finely stranded Class K copper construction with a durable abrasion resistant TPE (thermoplastic elastomer) insulation, engineered to withstand oil, gasoline, sunlight, saltwater, acids, and chemicals.
UL recognized as an AWM (Appliance Wiring Material), Arctic Ultraflex Blue® has become the preferred 600 volt flexible wire, commonly found in industrial automation, military technology, manufacturing, automotive, marine, and renewable energy—from recreational use to the development of the latest revolutionary technology.
* Occasionally stocked. Generally special order. Minimums may apply.
** Ampacities of 600V and 1000V 105°C AWM wires in air. Note: Ampacities based on single conductor in free air, 30°C (86°F) or 40°C (104°F) ambient temperature as specified, 105°C (221°F) conductor temperature, per table 310-17 of the NEC (adjusted for 105°C). Free air ratings assume a one-cable diameter spacing between adjacent conductors.
AWM stands for "Appliance Wiring Material," a standard designated by Underwriters Laboratories (UL) to indicate that our wire meets specific safety and performance requirements for use in various appliances and electronic equipment. AWM means that our wire has been designed and tested to meet stringent safety, durability, and performance standards in various applications, including general industrial and commercial use.
Class K stranding refers to the size and number of strands we use to construct our wire. Our Class K construction uses various numbers of 30 AWG strands to create our sizes. To see the the details on how many stands we put in each wire size, check out our Class K Conductors Table. Class K stranding contributes our wire's superior flexibility by flexing with our insulation and increases the conductivity of our by providing more strand surface area.
100% Copper Stranding is utilized in all our conductors for utmost quality and conductivity - we sell absolutely no copper clad wire. We stand by our dedication to quality utilizing only the finest conductor constructions to ensure our wire remains at the peak of performance in the wire and cable industry!
All of our 18 AWG to 10 AWG Arctic Ultraflex Blue® wire is stocked tin-plated for additional corrosion resistance. While we do not stock tin-plated Arctic Ultraflex Blue® constructions in our larger wire sizes, they may be available upon special order - minimums apply.

Yes! Many of our marine customers prefer Arctic Ultraflex Blue® in their projects for its superior performance and installation-friendly construction. However, though Arctic Ultraflex Blue® is arctic-grade, for inspected vessels and code compliancy stringent marine applications, we recommend our boat cable rated Multi Listed Flexible Wire. For multiconductor marine applications, we also carry a marine code compliant multiconductor Premium Boat Cable available in round and flat configurations!
We designed Arctic Ultraflex Blue® as a premium product for superior performance
Premium TPE Insulation
We designed a revolutionary flexible yet durable TPE insulation blend that is designed to perform in harsh cold weather conditions. However, due to the superior flexibility, Arctic Ultraflex Blue® has become the preferred premium flexible wire in nearly every industry and in many internal wiring applications.
Class K Stranding
To complement our premium insulation blend, we construct our conductors with 100% copper in a high-strand count, Class K configuration. Using various amounts of 30 AWG strands to construct our wire sizes, copper rods must be drawn out to 30 AWG and combined to create our conductor. For perspective, our 4/0 AWG construction has over 4000 strands! In addition, we utilize 100% copper stranding ensuring maximal conductivity and performance.
