Hydrolevel FOEM-3 Fitting Tee

The Hydrolevel FOEM-3 Fitting Tee (Part Number 45-305) is a specialized cast iron manifold fitting designed for integrating probes into hydronic or steam systems. Featuring a configuration of 1 1/4" x 1 1/4" x 3/4", this heavy-duty boiler manifold tee provides a stable mounting point for water level controls or temperature sensors without restricting fluid flow. Rated for a maximum pressure of 160 PSI, the FOEM-3 is a standard choice for contractors looking for a reliable low water cut-off fitting interface that can withstand industrial-grade service. Its precision-threaded 3/4" tapping ensures a leak-proof seal with compatible Hydrolevel probes or standard NPT sensors, while the 1 1/4" main ports maintain the volumetric capacity required in high-efficiency piping loops.

• Durable Cast Iron Construction: Built to handle the thermal expansion and contraction cycles common in hydronic heating systems.
• Optimized Probe Placement: Specifically engineered to position low water cut-off probes correctly within the flow path for accurate sensing.
• High Pressure Rating: Safely operates in systems up to 160 PSI, making it suitable for both residential and commercial manifold applications.
• Precise Threads: Features clean 1 1/4" and 3/4" NPT threading to simplify installation and reduce the risk of job-site leaks.

What probe series is compatible with the FOEM-3 fitting?
The FOEM-3 is typically used with Hydrolevel Safgard and HydroStat probe-style controls. Specifically, it accommodates the 3/4" NPT threads found on most standard probes, though you should always verify the insertion depth for your specific model.

Can this tee be used in steam boiler applications?
Yes, as a cast iron manifold fitting rated for 160 PSI, it is appropriate for steam or hot water systems, provided the system operating pressure does not exceed the component's maximum rating.

Does this fitting require a specific mounting orientation?
For low water cut-off applications, the tee should be installed so that the probe is horizontal or as per the controller manufacturer's instructions to ensure the sensor remains submerged at the proper water level.
