MIL-DTL-M22759/90 wires are light-weight, high-performance aerospace hookup wires with a dual-layer insulation of PTFE/polyimide/PTFE tape, covered with PTFE tape.They are similar to MIL-DTL-M22759/81 and /82 wires, but have thicker-wall insulation. These wires are designed for aerospace and other applications requiring excellent thermal stability and high break strength.
