It features a 2.5-inch dial face with a 0 to 100 psi range and delivers 1 percent of scale accuracy across that range. The stainless steel case provides corrosion resistance in demanding service environments. The gauge mounts via a 1\/4-inch NPT center back connection, making it straightforward to install inline or on a manifold port. Licensed plumbers, HVAC technicians, and pipefitters install this type of gauge for system commissioning, pressure testing, and ongoing operational monitoring.\u003c\/p\u003e\n\u003cp\u003eThis gauge is suited for residential and light commercial applications where a compact, reliable pressure indicator is needed. Typical installations include boiler systems, chilled water loops, compressed air lines, water supply lines, and hydronic heating systems. The dry (non-liquid-filled) construction keeps the design simple and weight low, appropriate for stable environments without heavy vibration or pulsation. The 2.5-inch dial provides a readable display in tight mechanical rooms or panel installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 100 psi pressure range suitable for common plumbing and HVAC system pressures\u003c\/li\u003e\n  \u003cli\u003e1 percent of scale accuracy for reliable pressure readings\u003c\/li\u003e\n  \u003cli\u003e2.5-inch analog dial for clear, at-a-glance readability\u003c\/li\u003e\n  \u003cli\u003eStainless steel case resists corrosion in wet or chemically active environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPT center back mount fits standard gauge ports and manifold taps\u003c\/li\u003e\n  \u003cli\u003eDry (non-liquid-filled) design for low-vibration service environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install pressure gauge for residential and light commercial systems using 1\/4-inch NPT gauge ports, including boilers, hydronic loops, compressed air systems, and water supply piping.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician following applicable local codes and ASME B40.100 gauge installation guidelines. Depressurize and isolate the system before removing or installing any gauge. Apply thread sealant or PTFE tape to the NPT threads before hand-tightening, then snug with a wrench — do not overtighten, as this can crack the gauge socket or distort threads. For systems with significant pressure pulsation, consider adding a snubber or isolator valve at the gauge port.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 100 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1 percent of scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Center Back\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ASHCROFT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 94889\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51541934571826,"sku":"94889","price":195.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354cb3162489ff68ea41d248e4d39263_2ab818a5-f335-4f90-9415-080516714d55.jpg?v=1785887966","url":"https:\/\/voomisupply.com\/products\/ashcroft-94889-pressure-gauge-2-5-in-100-psi-npt-back-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
