Value Brand Boiler Gauge Square 0-75 PSI 60-260°F

Square Boiler Gauge for Hydronic Systems

This square boiler gauge monitors both pressure and temperature on hydronic heating equipment. It reads zero to 75 psi and 60 to 260 degrees Fahrenheit, covering the normal operating envelope of residential and light-commercial boilers. The lower-back male NPT connection threads directly into standard boiler tappings. Technicians and facility managers use it to verify safe system conditions at a glance.

Sustained Readings with Stated Accuracy

Under continuous service the gauge maintains its published tolerance of plus or minus three-two-three percent on pressure and plus or minus three percent on temperature. The brass and bronze wetted parts resist corrosion from treated boiler water, while the glass lens and steel case withstand the heat and vibration of a running plant. No electronic components are present to drift or require recalibration over time.

Verify Connection and Range Before Ordering

Confirm that the boiler tapping accepts a half-inch male NPT fitting and that the lower-back orientation clears surrounding piping. Ensure the zero-to-75-psi span and 60-to-260-degree-Fahrenheit span match the design limits of the specific installation. Check local regulations for any restrictions related to the Proposition 65 warning on chemical content.
