Military specification (MIL-SPEC), aerospace grade, 600V rated, irradiated cross-linked Ethylene TetraFluoroEthylene (ETFE) thin wall insulation, 20 AWG with 19 / 32 stranded tinned copper hookup wire. Conforms to Mil-Spec MIL-W-22759/16-20-(color).

This wire is manufactured to the U.S. Department of Defense military specification (the world-wide standard) for the aerospace / defense industry. By law, it meets and exceeds rigorous manufacturing and testing requirements for wire used in high temperature, extreme environments. This ETFE insulation has better mechanical toughness than PTFE (Teflon) with the same extreme heat resistance. It is recommended to use good quality, sharp wire strippers and cutters.

If you are looking for the highest quality wire for building your new project, then this is your wire.
