It features a 4.5-inch analog dial with a measurement range of 0 to 15 psi and delivers 0.5% of scale accuracy, making it suitable for applications where precise pressure monitoring is critical. The thermoplastic case resists corrosion and impact, and the glass lens provides a clear, durable viewing surface. Connection is via a 1\/2-inch MNPT rear-entry fitting, and the rear flange mount configuration allows direct panel or wall mounting without additional brackets. Licensed HVAC technicians, plumbers, and process technicians install this gauge in both commercial and industrial settings.\u003c\/p\u003e\n\u003cp\u003eThis gauge is designed for process and industrial pressure monitoring in systems where a non-liquid-filled, rear-flange-mounted instrument is required. The rear MNPT connection makes it well suited for panel-mount installations, piping manifolds, and pressure monitoring stations in mechanical rooms, process lines, and HVAC systems. The IP66 and NEMA 4X ratings allow use in wet, washdown, and outdoor environments. The CRN certification supports use in Canadian pressure vessel and piping applications where provincial registration is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 15 psi measurement range with 0.5% of scale accuracy\u003c\/li\u003e\n  \u003cli\u003e4.5-inch analog dial for easy long-distance reading\u003c\/li\u003e\n  \u003cli\u003eThermoplastic case rated IP66 and NEMA 4X for wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eRear flange mount with 1\/2-inch MNPT connection for direct panel installation\u003c\/li\u003e\n  \u003cli\u003eNo-fill design eliminates liquid fill contamination concerns\u003c\/li\u003e\n  \u003cli\u003eCRN certified for Canadian pressure system compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style process pressure gauge for industrial and commercial piping systems requiring a 1\/2-inch MNPT rear-entry, rear-flange-mounted instrument in the 0 to 15 psi range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or instrumentation technician. Isolate and depressurize the system before removing any existing gauge or fitting. Apply appropriate thread sealant to the MNPT connection per the applicable piping code, such as the IPC or ASME B31.3, and tighten using a wrench on the gauge hex fitting only — do not torque against the dial housing. Verify system pressure is within the rated range of the gauge before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Type\u003c\/strong\u003e: Process Industrial Pressure Gauge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 15 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.5% of scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Rear Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Thermoplastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Glass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CRN, IP66, NEMA 4X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1279\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.5 pounds\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: 45-1279SS04L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51542822977842,"sku":"45-1279SS04L","price":261.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/760f8efc512ec2bc85a40aae2d63044d_2b470d10-f6f4-4e59-ab42-16d8957dad39.jpg?v=1785908443","url":"https:\/\/voomisupply.com\/products\/ashcroft-45-1279ss04l-pressure-gauge-0-15-psi-4-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
