Weil-McLain 510218097 – Combination Pressure and Temperature Gauge for EG Series Boilers
The Weil-McLain 510218097 is a direct replacement combination gauge for use in EG series water boilers. It provides simultaneous pressure (PSI) and temperature (°F) readings, enabling clear monitoring of system operating conditions. This OEM gauge is engineered for hydronic heating systems requiring accurate and consistent readout under varying load conditions.
The unit features a 2-1/2″ diameter dial with back 1/4″ NPT connection and extended shank length to accommodate standard mounting locations. It is constructed to deliver long-term performance in closed-loop systems where both pressure and temperature must be continuously monitored at the boiler manifold.

- Dual Measurement Function: Displays system pressure (0–75 psig) and water temperature (60–320°F) on a single dial face
- OEM Specification: Factory-designed replacement for EG series residential water boilers
- Clear Analog Display: 2-1/2 inch dial with dual scale for quick field diagnostics
- Threaded Connection: 1/4″ NPT back connection for standard boiler tap fittings
- Extended Shank: Long stem provides compatibility with recessed or hard-to-access port locations
