It features a 2.5-inch dial with a measurement range of -30 to 100 Hg, providing both vacuum and positive pressure readings on a single scale. The stainless steel case offers corrosion resistance in demanding environments. Accuracy is rated at 1 percent of scale, making it suitable for applications where reliable pressure indication is required. Licensed trades and service technicians install this gauge for system monitoring, commissioning, and diagnostics.\u003c\/p\u003e\u003cp\u003eThe ASHCROFT 83212 is suited for residential and light commercial HVAC systems, plumbing systems, compressor lines, and general fluid or gas service where a compact, lower-mount gauge is needed. The 1\/4 inch NPT lower-mount connection makes it compatible with standard threaded ports found on manifolds, tees, and pressure taps across a wide range of piping systems. It is a dry (non-liquid-filled) gauge, appropriate for low-vibration installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.5-inch analog dial for clear, at-a-glance pressure readings\u003c\/li\u003e\n\u003cli\u003e-30 to 100 Hg range covers vacuum and positive pressure in one gauge\u003c\/li\u003e\n\u003cli\u003e1 percent of scale accuracy for reliable system diagnostics\u003c\/li\u003e\n\u003cli\u003eStainless steel case provides corrosion resistance in harsh service conditions\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPT lower-mount connection fits standard piping ports\u003c\/li\u003e\n\u003cli\u003eDry gauge construction suited for stable, low-vibration installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new-installation gauge for systems with 1\/4 inch NPT lower-mount pressure ports, including HVAC, plumbing, and general mechanical piping applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician, plumber, or mechanical contractor. Isolate and depressurize the system completely before installing or replacing any pressure gauge. Apply thread sealant tape or pipe dope appropriate for the system media to the NPT threads before installation. Avoid over-tightening, which can crack the gauge body or distort the Bourdon tube.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Lower Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: -30 to 100 Hg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1 percent of scale\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\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: 83212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51544023761202,"sku":"83212","price":180.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca7ef3fc7c2c603b06e65000ba989cac.jpg?v=1785923116","url":"https:\/\/voomisupply.com\/products\/ashcroft-83212-pressure-gauge-2-5-in-dial-npt-lower-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
