ENFM 4104-2.5-4-10 Gauge

The ENFM 4104-2.5-4-10 is a heavy-duty industrial tridicator gauge designed for precision monitoring in hydronic heating systems and boiler applications. This dual-reading instrument features a 2.5-inch dial face that provides simultaneous measurements of system pressure from 0 to 75 PSI and water temperature across a range of 70°F to 320°F. Built with a 1/4" NPT back connection and a 0.95" probe length, this gauge is the direct replacement for 910-373-061, ensuring a seamless fit during maintenance or system overhauls. The robust construction includes a steel case and brass wetted parts to withstand the rigors of mechanical rooms and high-demand commercial environments. Technicians rely on this specific boiler pressure temperature gauge for its accuracy and its ability to fit into tight HVAC piping configurations thanks to its compact center-back mount design. This part is essential for diagnosing thermal expansion issues and maintaining proper static pressure levels within closed-loop heating circuits.

• Dual-Scale Monitoring: Provides real-time PSI and Fahrenheit readings on a single interface for efficient system diagnostics.
• Exact OEM Specifications: Serves as a standard 910-373-061 replacement, maintaining original equipment performance and alignment.
• High-Temperature Durability: Engineered for hot water boilers with a maximum operating temperature of 320°F.
• Rugged Build Quality: Features a corrosion-resistant brass connection and a durable black steel housing for long-term field use.
• Simplified Installation: The 1/4 inch NPT male connection allows for quick threading into existing hydronic manifolds or air eliminators.

Common Questions

Is this gauge compatible with potable water systems?
This gauge is designed specifically for non-potable hydronic systems and boiler internals. It is not intended for use in domestic drinking water applications.

What is the accuracy rating for the pressure and temperature scales?
The ENFM 4104 series typically adheres to industrial standards, offering a pressure accuracy of ±3-2-3% of span and temperature accuracy within ±3% of the full scale.

Can this replace a side-mount gauge?
No, this model features a center-back connection. If your current setup requires a side or bottom mount, plumbing adjustments or a different model would be necessary to ensure the dial face remains visible.
