Robertshaw 1970-060 Thermocouple

The Robertshaw 1970-060 is a heavy-duty, 60-inch Uni-Couple thermocouple designed for universal compatibility across a broad range of gas-fired pilot burners. Engineered for 20-30 millivolt (mV) systems, this unit features a stainless steel outer jacket that provides superior resistance to heat blistering and high-temperature oxidation in demanding combustion environments. The internal conductor utilizes a high-grade copper and nickel alloy for optimized electrical conductivity, ensuring a stable signal to the gas valve safety magnet. One of the primary advantages for field technicians is the versatile zip nut, which can be pushed, pulled, or threaded onto the rolled threads of the thermocouple, allowing for precision depth adjustment and secure seating in varied pilot brackets. This universal replacement thermocouple is a standard truck-stock item for servicing furnaces, boilers, water heaters, and commercial cooking equipment where extended lead lengths are required for proper routing and cold junction placement.

Key Benefits

• Universal Fitment: The Uni-Couple design and included Tinnerman clip ensure compatibility with nearly all OEM pilot burner configurations.
• Thermal Durability: The stainless steel tip and jacket extend the service life of the junction by preventing premature burn-through.
• Simplified Installation: The adjustable threaded zip nut allows for immediate positioning without specialized tools or custom brackets.
• Electrical Reliability: Integrated mica washers insulate the internal components to prevent shorting, maintaining a consistent millivolt output.
• High Compatibility: Frequently used as a direct replacement for brands like Honeywell, Johnson Controls, and ITT General Controls.

Common Questions

Can I use a 60-inch thermocouple to replace a shorter 24-inch or 48-inch model?
Yes, technically you can use a longer lead as long as the excess length is neatly coiled (avoiding sharp kinks) and secured away from direct heat or moving parts. However, for the most efficient millivolt transmission and cleanest installation, it is best to match the lead length as closely as possible to the original specifications.

What does the 20-30mV rating mean for my gas valve?
This rating indicates the open-circuit voltage produced by the thermocouple when heated by the pilot flame. Most standard standing pilot gas valves require a minimum of 13mV under load to hold the safety magnet open; this Robertshaw 1970-060 provides a robust 20-30mV range to ensure reliable safety circuit operation.

Why is my pilot light dropping out even with a new thermocouple installed?
Ensure the thermocouple tip is fully immersed in the top 1/2-inch of the pilot flame and that the coaxial connection at the gas valve is hand-tight plus a quarter turn. If the dropout persists, check for a "lazy" pilot flame or high resistance in the limit circuit.
