Robertshaw 1980-048 Thermocouple

The Robertshaw 1980-048 Snap-Fit Thermocouple is a high-performance 48-inch furnace and water heater component engineered for reliable pilot flame sensing in demanding HVACR applications. Designed for professional contractors, this 1980 Series thermocouple features a stainless steel outer jacket that provides superior resistance to heat blistering and oxidation at high ambient temperatures. The internal construction utilizes a precise combination of copper and nickel alloys to ensure maximum electrical conductivity and consistent millivolt output for gas valve engagement. A mica washer is integrated at the base to insulate against shorting conditions, while the brass sheath offers enhanced protection for the sensor head. The Robertshaw 1980-048 is a universal replacement part compatible with most residential and commercial pilot burners, including liquid propane (LP) systems and oxygen depletion sensors (ODS). Its snap-fit design, paired with an attached threaded nut and included Tinnerman clip, allows for efficient lead routing and secure terminal connection without the need for additional adapters.

• Universal Compatibility: Fits the majority of pilot burners across various brands, reducing the need to carry specialized inventory.
• Enhanced Durability: The stainless steel jacket prevents premature failure caused by high-heat environments and corrosive combustion byproducts.
• Simplified Installation: The snap-fit design and included mounting hardware streamline the replacement process in tight burner assemblies.
• Reliable Signal: High-grade alloys maintain a steady electrical signal to the gas valve, preventing nuisance shutdowns.
• Extended 48-Inch Reach: Ideal for larger appliance configurations where standard leads are insufficient for safe routing.

Is the Robertshaw 1980-048 compatible with LP gas systems?
Yes, this universal thermocouple is designed for use with both natural gas and liquid propane applications, specifically those requiring quick-dropout safety features.

Does this part require special adapters for installation?
The snap-fit series is engineered to install directly into most pilot burners using the attached threaded nut; no complicated adapters are necessary for standard replacements.

What causes a thermocouple to fail in a high-temperature application?
Failures are often caused by heat blistering of the outer jacket or shorting. The Robertshaw 1980-048 mitigates these risks with a stainless steel exterior and a mica insulating washer.
