M22759/32 Tefzel Wire

M22759/32 Lightweight Wall Cross-Linked ETFE Wire

This lightweight, high temperature airframe and avionics wires utilize an insulation of cross-linked, modified ethylene tetrafluoreothylene copolymer (ETFE). The insulation resists high PH cleaning fluids, fuels, lubricating oils, and many other chemicals. The wires can withstand temperature test extremes ranging from cold bend (-65°C) through (150°C) . These wires are a mechanically tough, flame retardant and weight saving solution to many aerospace applications.

Applications

MIL-W-22759/32 wires have crosslinked extruded ETFE insulation for aerospace and other applications requiring light weight, tight diameter tolerances, and enhanced mechanical toughness. Crosslinked ETFE insulation also provides exceptional resistance to radiation and chemicals

So what's the difference between /32 and /16 wire ?

The major difference between these two specifications of wire is the outer jacket, both /16 and /32 offer the same temp and voltage rating. Where these two differ are the types and amounts of Tefzel used.

M22759/16- Ethylene Tetrafluoroethylene (ETFE) 24 awg - 2/0 awg

  • Slightly larger O.D over /32 wire by roughly 15%*
  • Slightly heavier compared to /32 wire by roughly 20%*

M22759/32- Fluoropolymer Cross-linked Modified (ETFE)  30 awg -12 awg

  • Slightly smaller O.D over /16 wire by roughly 15%*
  • Slightly lighter compared to /16 wire by roughly 20%*

* Weight and O.D. comparisons based on 24 ga.
