Utica-Dunkirk FE3980B840 Gauge
The Utica-Dunkirk FE3980B840 Gauge is a professional-grade D.40 pressure/temperature gauge specifically engineered for high-performance hydronic systems, including the Ccb150 and Chb100/130+ boiler series. This dual-function hydronic boiler gauge provides simultaneous, real-time monitoring of system PSI and water temperature, allowing technicians to verify that the equipment is operating within the manufacturer’s specified safety limits. Built with a durable stainless steel body and a clear, high-contrast face, the FE3980B840 ensures accurate diagnostics even in high-vibration environment. This genuine Utica Dunkirk boiler part is essential for maintaining proper boiler pressure settings and preventing thermal shock or system over-pressurization. Designed for direct integration into the supply piping, it utilizes a standard connection that allows for a straightforward swap with of the OEM replacement gauge. Using this precision-calibrated instrument ensures the long-term reliability and peak efficiency of the heating loop while simplifying the routine inspection process for service contractors.
Key Benefits- Dual-Scale Monitoring: Provides immediate readings for both system pressure (PSI) and temperature (°F) on a single dial for efficient diagnostics.
- OEM Compatibility: Specifically designed as a direct Utica-Dunkirk replacement part for Ccb150 and Chb100/130+ models to ensure precise fitment.
- Rugged Construction: Features a corrosion-resistant stainless steel body and robust internal mechanisms to withstand harsh boiler room conditions.
- Increased System Safety: Helps prevent high-limit lockouts and pressure relief valve discharge by providing accurate real-time data.
- Which boiler models is this gauge compatible with? This unit is built for Utica and Dunkirk systems, specifically compatible with the Ccb150 and Chb100/130+ series boilers.
- Can I use a wrench to tighten the gauge during installation? Yes, use a 9/16” open-end wrench on the brass hex portion of the shaft; avoid tightening by the gauge head to prevent internal damage.
- Should I use thread sealant when installing the FE3980B840? Yes, a small amount of high-quality pipe dope or Teflon tape should be applied to the threads to ensure a leak-proof seal.
