Thermocouple Wire and Extension Wire - Single Pair

PFA Insulated Parallel Construction Thermocouple Wire

  • PFA is ideal for higher temperature applications up to 480°F when Heat Resistant PVC is not adequate
  • Withstands attack from virtually all known chemicals, oils and fluids. All our PFA cables are gas, steam and water tight which makes them most suitable for applications such as autoclaves or sterilizers
  • A wide variety of constructions from simple twisted pairs to shieldeded types in virtually all the thermocouple combinations
PFA Parallel Twin
