The 3.5-inch analog dial provides clear readability in the field, while the liquid-filled design dampens pointer vibration and reduces wear on the Bourdon tube mechanism. The case is stainless steel and the Bourdon tube is constructed from 316 stainless steel, making the gauge well-suited for corrosive or wet environments. Accuracy is rated at 1 percent of scale. The 1\/4-inch NPT lower mount connection allows direct inline installation on pipework, manifolds, or equipment panels. The polycarbonate lens protects the dial face from impact and moisture. Plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals install this gauge as part of system pressure monitoring.\u003c\/p\u003e\n\u003cp\u003eThe ASHCROFT 94221 is designed for industrial pressure monitoring on water, gas, oil, and compatible fluid systems where consistent accuracy and corrosion resistance are required. The lower mount NPT configuration fits standard threaded ports found on pressure manifolds, pump assemblies, filter housings, and process piping. The liquid-filled construction is particularly valuable on systems subject to pulsation, vibration, or pressure spikes. The 3.5-inch dial size suits both panel-mounted and direct-pipe installations in mechanical rooms, equipment yards, and utility spaces. Certifications include CRN, IP54, IP65\/NEMA 4, PED, and RoHS, supporting use in a broad range of regulated environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 1000 psi pressure range with 1 percent of scale accuracy\u003c\/li\u003e\n  \u003cli\u003eLiquid-filled design dampens vibration and extends Bourdon tube service life\u003c\/li\u003e\n  \u003cli\u003e316 stainless steel Bourdon tube for corrosion resistance in harsh service\u003c\/li\u003e\n  \u003cli\u003e304\/316 stainless steel case construction\u003c\/li\u003e\n  \u003cli\u003e3.5-inch analog dial for clear field readability\u003c\/li\u003e\n  \u003cli\u003eCertified to CRN, IP54, IP65\/NEMA 4, PED, and RoHS standards\u003c\/li\u003e\n  \u003cli\u003ePolycarbonate lens protects dial from impact and moisture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install industrial pressure gauge for 1\/4-inch NPT lower mount applications on process piping, pump systems, and pressure manifolds requiring a 0 to 1000 psi range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician. Shut off system pressure and bleed residual pressure before removing or installing any gauge. Apply thread sealant or PTFE tape to the NPT connection per applicable plumbing and mechanical codes. Do not overtighten the connection, as this can crack the gauge socket or distort the Bourdon tube.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 1000 psi\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 Diameter\u003c\/strong\u003e: 3.5 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 Thread\u003c\/strong\u003e: 1\/4 inch 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\u003eWeight\u003c\/strong\u003e: 2 pounds\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\u003eSeries\u003c\/strong\u003e: 1009\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: 94221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51544230625586,"sku":"94221","price":229.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354cb3162489ff68ea41d248e4d39263_399e37ab-dfde-40db-8bc0-cd3d6615f4a5.jpg?v=1785925990","url":"https:\/\/voomisupply.com\/products\/ashcroft-94221-pressure-gauge-0-1000-psi-3-5-in-dial","provider":"Voomi Supply","version":"1.0","type":"link"}
