Utica-Dunkirk 240005246 Tridicator

The Utica-Dunkirk 240005246 Tridicator is a professional-grade boiler temperature and pressure gauge designed for precise hydronic system monitoring. Engineered as the direct replacement for 146-23-009-70, this OEM component ensures exact compatibility with Utica and Dunkirk boiler series. It features a high-visibility dial face with a temperature range of 70 to 320 degrees F and a pressure scale of 0 to 75 PSI. The 5-inch stem length provides accurate sensing within the fluid stream, making it a reliable HVAC replacement part for contractors maintaining residential and commercial heating systems. Utilizing a standard 1/4 inch NPT connection, this combination pressure/temperature gauge allows technicians to verify system performance and safety parameters at a glance. Whether you are performing a routine inspection or a critical repair, the 240005246 tridicator delivers the rugged build quality required for high-temp hydronic environments.

• Dual-Function Monitoring: Provides simultaneous readings for boiler system pressure and water temperature, streamlining diagnostic workflows.
• Precise OEM Fit: Designed as a drop-in Utica Dunkirk replacement part, eliminating the need for pipe modifications or adapters.
• Extended Sensing Probe: The 5-inch shank ensures the sensor is properly submerged to record real-time fluid temperatures rather than ambient pipe heat.
• Durable Construction: Built for the rigors of mechanical rooms, capable of handling sustained 75 PSI operating pressures.

Is the 240005246 compatible with older Dunkirk models?
Yes, this tridicator gauge is the authorized replacement for the 146-23-009-70 sensor commonly found in Dunkirk and Utica boilers. Always verify the 1/4" NPT connection size before installation.

What are the primary indicators on the dial?
The face includes scales for temperature (Fahrenheit) and pressure (PSI), allowing contractors to quickly identify if a system is operating outside its designed hydronic pressure limits.

Will this work for a 30 PSI steam system?
While the scale reaches 75 PSI, this unit is primarily used in water-based hydronic systems. Always check your specific boiler's manual to ensure the 70-320F range meets your application’s thermal requirements.
