Weil McLain 510-218-045 2.5" Steam Pressure Gauge 1/4" NPT Male Inlet 0-3 PSIG

The Weil McLain 510-218-045 Steam Pressure Gauge is a 2.5-inch back-mount instrument that measures steam pressure within 030 PSI range and provides a clear visual reading during equipment operation. Internal pressure acts on the gauge mechanism, moving the pointer across the calibrated scale to display the current pressure level. The pressure indication supports proper monitoring in HVAC systems and enables timely operating adjustments, assists with routine inspection and confirms that the steam circuit is operating within intended pressure range. It is threaded into a 1/4-inch pressure port, allowing the direct contact with the steam circuit for proper measurement.
