It features a 3.5-inch dial face for easy reading in the field and a lower-mount 1\/4-inch NPT connection for direct installation into process lines, manifolds, or system ports. The gauge reads a vacuum range of 30 to 0 inches of mercury (Hg) with 1 percent of scale accuracy. The stainless steel case provides durability in environments with moisture, mild corrosives, or mechanical vibration. This gauge is dry (non-liquid-filled), making it straightforward to install and service.\u003c\/p\u003e\n\u003cp\u003eThe ASHCROFT 95099 is suited for residential and light commercial HVAC systems, refrigeration service, and plumbing applications where vacuum or negative pressure monitoring is required. The lower-mount NPT connection allows for panel-mount or inline installation at the base of the gauge. Licensed HVAC technicians and plumbers use this style of gauge for monitoring system vacuum levels, checking line pressure, and verifying system integrity during commissioning or service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.5-inch analog dial for clear field readability\u003c\/li\u003e\n  \u003cli\u003eVacuum range: 30 to 0 inches Hg\u003c\/li\u003e\n  \u003cli\u003e1 percent of scale accuracy\u003c\/li\u003e\n  \u003cli\u003eLower-mount 1\/4-inch NPT connection for direct inline or panel installation\u003c\/li\u003e\n  \u003cli\u003eStainless steel case for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eDry (non-liquid-filled) construction for easy servicing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service gauge for HVAC, refrigeration, and plumbing systems requiring a 1\/4-inch NPT lower-mount vacuum gauge with a 3.5-inch dial.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or plumbers. Isolate and depressurize the system fully before removing or installing any pressure gauge. Apply thread sealant appropriate for the service medium to the NPT threads and tighten to hand-tight plus a modest wrench turn — do not overtighten, as this can damage the gauge socket. Verify the gauge range is appropriate for the system pressure before placing the system back in service.\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 (vacuum)\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 Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\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\u003eLiquid Filled\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 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: 95099\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51538388943154,"sku":"95099","price":206.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354cb3162489ff68ea41d248e4d39263_84e0c420-e293-45f0-bb2c-09da2cee2428.jpg?v=1785824166","url":"https:\/\/voomisupply.com\/products\/ashcroft-95099-pressure-gauge-3-5-in-dial-npt-lower-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
