Weil McLain 510-218-045 2.5" Steam Pressure Gauge 0/30 PSI 1/4" Back Mount

The Weil McLain 510-218-045 Steam Pressure Gauge measures the steam pressure levels within boiler assemblies to maintain accurate operating readings during heating operation. Its internal pressure-sensing mechanism converts system pressure changes into needle movement across the 2.5-inch dial for continuous visual indication. The gauge connects through a 1/4-inch NPT fitting and supports back or bottom mount orientation for integration into steam boilers and hydronic HVAC systems where pressure observation is required during maintenance or troubleshooting. Clear dial visibility assists with system calibration, pressure verification, and operational assessment of steam circulation equipment used in institutional, multi-unit, and process heating conditions.
