Weil-McLain 380000000 – Combination Pressure and Temperature Gauge Kit
The Weil-McLain 380000000 gauge kit is a factory replacement component used to monitor both pressure and temperature in hydronic heating systems. Designed for compatibility with select Weil-McLain boiler models, this combination gauge includes a dual-scale dial with a rear (back) 1/4″ NPT connection and a short stem for direct mounting into system tappings.
This kit provides accurate, real-time system readings, assisting with diagnostics, system balancing, and safe boiler operation. A reducing bushing is included for installations requiring 1/2″ NPT adaptation.
Key Features
- Dual-Function Dial: Simultaneously displays system pressure (psi) and temperature (°F)
- Pressure Range: 0–75 psi
- Temperature Range: 60–320°F
- Back Mount Connection: 1/4″ NPT, suitable for panel or boiler tapping installation
- Included Bushing: 1/4″ x 1/2″ NPT reducing bushing included for field adaptability
- Dial Size: 3-1/8 inch diameter for clear visibility

- Ideal for hydronic heating systems requiring combined temperature and pressure monitoring
- Direct OEM replacement for original Weil-McLain assemblies using this configuration
Installation Notes
Gauge should be installed in an accessible tapping with adequate clearance for the 3-1/8″ dial face. Use thread sealant compatible with water and heat. Avoid overtightening to prevent damage to the stem or gauge housing. Installation should be performed with the system depressurized and cooled.
Although installation is straightforward, final positioning of the dial face and accurate seating of the sensor stem are important for reliable readings. The included bushing accommodates installations requiring a 1/2″ NPT interface.
