It features a 2.5-inch analog dial with a 0 to 30 psi range and delivers 1% of full-scale accuracy. The lower-mount, 1\/4-inch NPT connection makes it a direct-fit choice for inline installations on pipes, manifolds, and service ports. The stainless steel case and polycarbonate lens protect the internals against moisture, vibration, and light chemical exposure. Liquid filling dampens needle flutter in high-vibration or pulsating-flow systems, extending service life and improving readability on the job.\u003c\/p\u003e\u003cp\u003eThis gauge is suited for residential and light commercial plumbing, HVAC hydronic systems, compressed air lines, refrigeration service manifolds, and industrial process piping where low-range pressure measurement is required. The lower-mount configuration fits standard panel-mount and pipe-mount installations where the connection point is at the bottom of the gauge. Licensed plumbers, HVAC technicians, and industrial maintenance mechanics are the primary installers. The 2.5-inch dial size provides clear readability in confined mechanical spaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0 to 30 psi range with 1% of full-scale accuracy for precise low-pressure readings\u003c\/li\u003e\n\u003cli\u003eLiquid-filled case reduces needle flutter in vibrating or pulsating service\u003c\/li\u003e\n\u003cli\u003e316 stainless steel Bourdon tube resists corrosion in wet and mildly aggressive media\u003c\/li\u003e\n\u003cli\u003e304\/316 stainless steel case with polycarbonate lens rated IP54 and IP65\/NEMA 4\u003c\/li\u003e\n\u003cli\u003e1\/4-inch lower-mount NPT connection for standard pipe and manifold installations\u003c\/li\u003e\n\u003cli\u003eCompliant with CRN, PED, and RoHS standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and aftermarket replacement industrial pressure gauge for lower-mount, 1\/4-inch NPT plumbing, HVAC hydronic, compressed air, and light process piping applications requiring a 0 to 30 psi analog dial instrument.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified industrial mechanic. Isolate and depressurize the system fully before removing an existing gauge or threading in the new one. Apply thread sealant or PTFE tape to the NPT threads in accordance with IPC and IFGC guidelines — do not overtighten, as this can crack the gauge socket. On liquid-filled gauges, verify the fill plug is intact and the dial is oriented correctly before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 30 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1% of full 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\u003eMount Type\u003c\/strong\u003e: Lower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/4 inches NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBourdon Tube Material\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel (304\/316)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Polycarbonate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e: IP54, IP65\/NEMA 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CRN, IP54, IP65\/NEMA 4, PED, RoHS\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: 94474\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51542702293298,"sku":"94474","price":207.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69cc5ee26e12c175900f8a55bd544d7c.jpg?v=1785904762","url":"https:\/\/voomisupply.com\/products\/ashcroft-94474-pressure-gauge-0-30-psi-2-5in-dial-lower-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
