It features a 3-inch dial with a pressure range of -30 to 0 inches Hg and delivers 0.5% of scale accuracy. The stainless steel case resists corrosion, making it suitable for demanding mechanical, HVAC, refrigeration, and industrial service environments. The 1\/4-inch lower-mount NPT connection threads directly into standard ports for a clean, in-line installation. This gauge is installed by HVAC technicians, plumbers, pipefitters, and mechanical contractors who need reliable vacuum readings in process or system monitoring applications.\u003c\/p\u003e\n\u003cp\u003eThe ASHCROFT 92918 is suited for residential and light commercial HVAC systems, refrigeration lines, vacuum systems, and general plumbing or mechanical installations where vacuum pressure monitoring is required. The lower-mount configuration positions the dial face upright for easy reading when the gauge is installed in a panel, manifold, or pipe riser. The 1\/4-inch NPT thread is a common connection size found across a wide range of system components, valves, and fittings in trade applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVacuum range of -30 to 0 inches Hg for negative-pressure monitoring\u003c\/li\u003e\n  \u003cli\u003e0.5% of scale accuracy for precise system diagnostics\u003c\/li\u003e\n  \u003cli\u003e3-inch analog dial for clear, at-a-glance readings\u003c\/li\u003e\n  \u003cli\u003eStainless steel case for corrosion resistance in wet or chemical environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPT lower-mount connection fits standard trade fittings and manifolds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install vacuum gauge for HVAC, refrigeration, plumbing, and mechanical systems using standard 1\/4-inch NPT lower-mount gauge ports.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician, pipefitter, or plumber. Shut down and depressurize the system fully before removing an existing gauge or threading in this unit. Apply appropriate thread sealant to the NPT threads per the applicable installation code. Do not overtighten the connection; use a wrench on the gauge hex fitting only, not on the dial body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: -30 to 0 inches Hg\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.5% of scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 3 inches\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: Lower\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\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: 92918\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51543550132530,"sku":"92918","price":386.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f7c5f484491181f75ee0f49f49b2ece_69e11ba8-55a9-4872-9d70-e166101935b6.jpg?v=1785920302","url":"https:\/\/voomisupply.com\/products\/ashcroft-92918-pressure-gauge-3-in-npt-lower-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
