Ashcroft 25-1009-SW-02B-100 is a 2.5-inch Duralife pressure gauge with a stainless steel case, a 0–100 psi range, and a 1/4" NPT back connection; it comes with a mounting bracket for quick, secure installation. This 1009 series gauge uses PowerFlex movement for improved resistance to vibration and pulsation and offers True Zero to reduce reading errors. In dry service, its accuracy is ±1% of span (ASME B40.100 Grade 1A); some configurations are liquid-filled (±1.5% of span) for dynamic applications. Typical industrial uses include pumps and compressors, boilers, equipment skids, ammonia and refrigeration services.
