Standard J-type Thermocouple Wire with High Temperature PFA Insulation

- 10 yard (30 ft or 9.2 meter) or multiples -


This is a J-type thermocouple wire with black Teflon PFA (perfluoroalkoxy) insulation, which is stable up to about 260 °C or 500 °F. This J-type thermocouple wire can be used to make your own Type J thermocouples for a wide range of applications, or to make your own Type J thermocouple extension wire. The iron / constantan wire is made to standard J-type thermocouple specifications. This is a a solid wire and therefore especially useful for J-type thermocouples, but also can be used for extension wires. It is sold in 10 yard increments, so if you order 2 units of this, you will receive a single 20 yard long wire.


  • J-type Thermocouple wire for making thermocouples or extension wires
