It features a 2.5-inch stainless steel dial face with a range of 30 inches of vacuum to 100 psi and delivers 1% of scale accuracy. The liquid-filled case dampens needle vibration and protects internal components in high-pulsation or vibration-prone environments. Licensed plumbers, HVAC technicians, and mechanical contractors install this gauge where a reliable, at-a-glance pressure reading is required on liquid or gas systems.\u003c\/p\u003e\u003cp\u003eThis gauge is suited for residential and light commercial applications including water supply lines, boiler systems, compressed air systems, and hydronic heating loops. The lower-mount NPT connection allows direct inline installation on pipes, manifolds, or tee fittings. The 2.5-inch dial provides sufficient readability for panel or equipment installations where close viewing distance is expected. Its stainless steel case resists corrosion in wet or chemically aggressive environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLiquid-filled case reduces needle flutter in high-vibration or pulsating-pressure applications\u003c\/li\u003e\n\u003cli\u003e1% of scale accuracy supports reliable system diagnostics and pressure verification\u003c\/li\u003e\n\u003cli\u003e2.5-inch analog dial for clear, at-a-glance readability\u003c\/li\u003e\n\u003cli\u003eLower-mount NPT thread for straightforward inline pipe installation\u003c\/li\u003e\n\u003cli\u003eStainless steel case for corrosion resistance in wet or harsh environments\u003c\/li\u003e\n\u003cli\u003eVacuum-to-pressure range: 30 inches of vacuum to 100 psi, suitable for dual-service monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation pressure gauge for residential and light commercial plumbing, HVAC, and mechanical piping systems requiring a 0.25-inch NPT lower-mount connection and a 100 psi range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified mechanical technician in accordance with applicable local codes and ASME B40.100 guidelines. Shut off and depressurize the system completely before removing or installing the gauge. Use appropriate thread sealant on the NPT connection and avoid over-tightening, which can crack the socket or distort the bourdon tube. Do not exceed the gauge maximum pressure rating during system pressure tests.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 30 inches of vacuum to 100 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1% 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: 2.5 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: 0.25 inches\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 83216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51544577540402,"sku":"83216","price":265.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354cb3162489ff68ea41d248e4d39263_7ea0b56a-7ff2-49fe-815b-f84a8ada8dcf.jpg?v=1785930499","url":"https:\/\/voomisupply.com\/products\/ashcroft-83216-pressure-gauge-100-psi-2-5in-dial-npt-lower-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
