Thermocouple Wires

Micro-Tek offers a variety of thermocouple wire constructions to suit individual customer or project requirements. Standard types available are Type K, J and T, other types are available on special order. The conductors are available in thermocouple grade or extension grade and standard or special limits of error (SLE). Micro-Tek offers insulation colors to meet ANSI and IEC coding. Current insulation materials in stock are PTFE, PFA and FEP. These can be used in combinations to meet the temperature requirements of a customer’s need.

Constructions available

  • Single Insulated Strands
  • Side By Side Duplex
  • Twisted Pair or Multiple Twisted Pairs
  • PTFE Single Shot

Conductor Sizes from #18AWG to #40AWG

Insulation Thickness from 0.002″ in PTFE, PFA and FEP

Shielding currently available in Stainless Steel

Overall Jacketing available in PTFE, PFA and FEP

Our engineering expertise and range of manufacturing capabilities are unmatched in the industry.

Extruding fluoropolymer resins PTFE, FEP, PFA and ETFE on various nonferrous, ferrous, plated, un-plated, thermocouple and alloy wires in single end, concentric, roped and various configurations.


Micro-Tek are specialist high performance, extreme environment wires.
We are a technology leader in high-temperature fluoropolymer extrusion and materials used in the manufacture of specialist high-performance cables that operate in extreme environments. Our range covers thermocouple cables, extension wires, high flex braided, equipment wires & cables, multicore cables, micro coaxial cables, braided cables and fine wires & stranding. Our cables can be manufactured to be resistant to flame, oils, chemicals, cryogenic and even operate in ultra-high vacuum (UHV) which can be made radiation resistant for nuclear.
