m16878/11/12/13 wires

What are M16878/11, M16878/12, and M16878/13 Wires?

MIL-W-16878/11, MIL-W-16878/12, and MIL-W-16878/13 are all types of mil-spec wire and share a lot of similar properties. However, they vary slightly when looked at more closely.

All three wires are insulated with Fluorinated Ethylene Propylene (FEP). FEP insulation works very well in high-temperatures, is the most flexible of all insulations, resists moisture absorption, and resits atomic oxygen erosion, making it able to withstand extreme conditions. All three wires have a minimum temperature rating of -55°C to +150°C (200°C with a Silver-Coated Copper Conductor).

All of these wires also feature tinned copper conductors but have silver-coated copper conductors as an available option. Additionally, they all pass the UL VW-1 Flame Test, which tests the material’s ability to resist fire along a vertically suspended wire.

Lastly, all three wires can also be used in applications with electronic equipment and computer back panels, and are able to be customized with our value-added services of striping, cutting, printing, and twisting.

These wires seem similar, but they aren't identical. Some of their differences include:

  • MIL-W-16878/11 (NEMA HP4 Type K): has a .010 Nominal Wall Thickness, a voltage rating of 600, and is available in 8-32 AWG. 
  • MIL-W-16878/12 (NEMA HP4 Type KK): has a .015 Nominal Wall Thickness, a voltage rating of 1000, and is available in 2-32 AWG.
  • MIL-W-16878/13 (NEMA HP4 Type KT): has a .006 Nominal Wall Thickness, a voltage rating of 250, and is available in 20-36 AWG.
