It features a 3.5-inch analog dial with a 0 to 600 psi range and delivers 1 percent of scale accuracy. The gauge mounts from the lower connection using a 1\/4-inch NPT thread. The stainless steel case and 316 stainless steel Bourdon tube make it suitable for corrosive environments and wet locations. Liquid filling dampens pointer vibration and protects internal components from pulsating pressure lines. Licensed plumbers, pipefitters, HVAC technicians, and process mechanics are the typical installers for this gauge.\u003c\/p\u003e\n\u003cp\u003eThis gauge fits residential and commercial installations where reliable pressure monitoring is required on gas, water, steam, or hydraulic lines within its rated range. The lower-mount configuration positions the connection at the six-o-clock position on the gauge body, which suits panel mounting and direct pipe-thread installation on vertical runs. The polycarbonate lens provides a clear reading surface while resisting impact. Its compliance with CRN, IP54, IP65\/NEMA 4, PED, and RoHS standards makes it appropriate for a broad range of regulated industrial and mechanical system applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 600 psi range with 1 percent of scale accuracy for reliable pressure monitoring\u003c\/li\u003e\n  \u003cli\u003eLiquid-filled housing dampens vibration and protects the Bourdon tube on pulsating lines\u003c\/li\u003e\n  \u003cli\u003e316 stainless steel Bourdon tube and 304\/316 stainless steel case resist corrosion\u003c\/li\u003e\n  \u003cli\u003eLower-mount 1\/4-inch NPT connection for direct pipe-thread or panel installation\u003c\/li\u003e\n  \u003cli\u003ePolycarbonate lens offers impact resistance and clear dial visibility\u003c\/li\u003e\n  \u003cli\u003eRated to IP54 and IP65\/NEMA 4 for wet and washdown environments\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 mechanical, HVAC, plumbing, and process piping systems requiring a 1\/4-inch NPT lower-mount connection and a 0 to 600 psi measurement range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified mechanic in accordance with applicable local codes and ASME B40.100 guidelines for pressure gauges. Shut off and depressurize the system completely before removing an existing gauge or installing this unit. Apply an appropriate thread sealant to the NPT connection and tighten to hand-tight plus the recommended turns per the pipe fitting standard — do not over-torque the stainless steel threads. Verify the line pressure is within the 0 to 600 psi rated range before returning the system to service.\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 600 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\u003eThread Size and Type\u003c\/strong\u003e: 1\/4 inches 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: 94491\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51542063448370,"sku":"94491","price":229.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5caa7dded3d2c089546a0096ff5bd5f4.jpg?v=1785890943","url":"https:\/\/voomisupply.com\/products\/ashcroft-94491-pressure-gauge-0-600-psi-3-5-in-dial-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
