Lochinvar & A.O. Smith 100376494 Gauge
The Lochinvar & A.O. Smith 100376494 is a professional-grade Temperature & Pressure (T&P) Gauge designed for precise monitoring in high-demand hydronic and potable water systems. As the direct OEM replacement for the discontinued 100208153, this commercial water heater gauge provides critical real-time diagnostics to ensure safe boiler operation. Featuring a dual-scale interface, it delivers accurate pressure readings from 0-75 PSI and temperature measurements from 50-320°F. Built with a 1/2" NPT connection, this HVAC replacement part is engineered for a secure, leak-free fit in Lochinvar boilers and A.O. Smith storage tanks. Veterans in the field rely on this system monitoring gauge for its thermal accuracy and durability in both residential and industrial heating loops. By maintaining strict oversight of internal vessel conditions, this component helps prevent over-pressurization and overheating, ensuring your equipment stays within specified mechanical tolerances during peak cycles.
Key Benefits:- Direct OEM Matching: Drop-in 100208153 replacement ensures factory-spec fitment without the need for piping modifications.
- High-Contrast Dual Scale: Provides simultaneous tracking of pressure and temperature for faster troubleshooting and system balancing.
- Industrial Build Quality: Designed to withstand the rigorous thermal cycling common in hydronic heating systems and commercial boilers.
- Precision Calibration: Reliable 0-75 PSI and 50-320°F ranges allow for fine-tuned control of system safety parameters.
Is this gauge compatible with older A.O. Smith models?
Yes, the 100376494 is the standard OEM replacement for a wide range of Lochinvar and A.O. Smith units specifically requiring a 1/2" NPT connection and the 50-320°F range.
Does this part replace the 100208153?
Correct. This is the official successor to the 100208153, maintaining the same technical specifications and physical dimensions for a seamless swap.
What is the thread size for installation?
This unit features a standard 1/2" NPT male thread, which is the most common size for commercial temperature and pressure ports.
