The Weil-McLain 383700376 is a bottom water return pipe with an integrated sensor tapping designed for hydronic heating boilers. This piping component directs return water back into the boiler loop while providing a dedicated connection port for system monitoring instrumentation.
Return piping components maintain the closed hydronic circuit between system radiation and the boiler. Incorporating a dedicated sensor tapping allows temperature sensors or monitoring probes to seat directly within the return fluid flow for accurate system tracking.
Key Performance Features:
- Integrated Sensor Tapping: Features a built-in port to mount temperature or diagnostic sensors directly in the return stream.
- Model Designation: Configured for Weil-McLain ECO Tec - Series 1 and ECO Tec - 80 equipment.
- Return Path Connection: Serves as the bottom water return conduit to maintain proper fluid circulation within the unit.
Application: Designed for Weil-McLain ECO Tec - Series 1 and ECO Tec - 80 boilers. Please confirm the part number against your existing part or unit documentation, or send your model and serial number to National Boiler Supply to verify before ordering.
