⚫ 20 Ga. Type "J" Thermocouple Wire
✅ Thermocouple grade Type J extension wire
✅ 20 AWG solid conductors for stable signal transmission
✅ Teflon insulation rated to 500°F (260°C)
✅ Industry-standard ANSI color coding
✅ White positive conductor is magnetic (Iron)
✅ Ideal for extending Type J thermocouple circuits
