WesBell Type E wire is also known as M16878/4 wire and PTFE wire. It’s rated for 600 volts and higher than normal temperature of 200C. Type E wire is commonly used in electrical and electronic applications where high temperature is encountered.

Type E wire provides all the advantages of most standard hookup wires with added durability in extreme temperatures. The PTFE provides a high-temperature jacket that handles heat much better than electrical or PVC wires.

M16878/4 Wire Construction

Our 20 AWG Type E wire is silver-plated with copper strands and a single layer of PTFE insulation. It is resistant to most potential damage from soldering irons, thermal aging, open flames, solvents, moisture, grease, ozone and other harmful chemicals.

This wire has low power loss and is ideal for higher frequency assemblies and high-temperature internal electronics. Compared to other thicker insulations, the medium-wall PTFE saves space and weight, allowing for easier product assembly. The durable structure offers high reliability, excellent thermal stability and it’s also environmentally safe.

Approvals include:

  • CSA.
  • M16878/4.
  • RoHS.
  • UL1213.

Type E Wire Applications

MIL-W-16878 is a military spec for harness applications and the internal wiring of electronic equipment. This wire is popular because of its size, cost-effectiveness, non-flammable materials and resistance to chemicals. While some of the M16878 military specifications have become obsolete, the M16878 name has stuck throughout the industry.

Type E high-performance wires meet the requirements for low-flame propagation, high-temperature resistance, small dimensions and low weight. Typical uses for the M16878/4 wire include harness applications for the military or aerospace industry, power supply lead wire and internal wiring in electronic equipment.
