Thermocouple Wire

We stock the most reliable thermocouple wire for optimal performance. Our wiring insulation materials include fiberglass, FEP and PVC. Braided fiberglass exterior insulation serves as a high intensity heat shield in a range of applications. Our fiberglass thermocouple-grade wire withstands temperatures up to 900°F. Order it in Type J and K, with color coding for fast identifications. We make it easier to utilize stock thermocouple wiring to fabricate assemblies or connect a thermocouple assembly to devices, such as a temperature controller. Quickly coordinate your sensing device type to wire type. Examples of our 20-gauge wire, J and K wire include:

  • Fiberglass: Features braided fiberglass insulation for intense heat protection, with maximum temperature of 900°F and a stainless steel over-braid option.
  • FEP (Teflon): Insulation for up to 400°F max temperature. Moisture resistance available.
  • PVC: Polymer insulation for up to 220°F.

Field-Proven Thermocouple Extension Wire

We offer thermocouple extension wire that has been diligently tested for excellence on the job. Thermocouple wire creates the sensing point for temperature measurements. It differs from extension wire, which extends a signal from the thermocouple to instruments. The insulation material is a key parameter in considering which thermocouple wire to use. Teflon and fiberglass insulation is found in our thermocouple-grade wire, while PVC wire often serves as extension-grade wire for thermocouples.
