It features a 4.5-inch analog dial with a 0 to 600 psi range and delivers 0.5% of scale accuracy. The case is aluminum construction, and all wetted parts are stainless steel for corrosion resistance in process environments. The glass lens and no-fill design keep maintenance straightforward. This gauge is installed by licensed plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals who need reliable pressure monitoring on process lines and mechanical systems.\u003c\/p\u003e\n\u003cp\u003eThis gauge is suited for process piping, industrial fluid systems, and commercial or industrial HVAC and plumbing installations where a rear flange mount is required. The 0.5-inch MNPT rear connection allows direct in-line mounting to threaded process connections. The rear flange mount provides panel or surface mounting capability, making it practical for control panel integration or bulkhead installations. The no-fill design simplifies handling in environments where liquid-filled gauges are not preferred or permitted.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5-inch analog dial with 0 to 600 psi pressure range\u003c\/li\u003e\n  \u003cli\u003e0.5% of scale accuracy for precise pressure readings\u003c\/li\u003e\n  \u003cli\u003eStainless steel wetted parts for corrosion resistance in process fluids\u003c\/li\u003e\n  \u003cli\u003eAluminum case construction for reduced weight and durability\u003c\/li\u003e\n  \u003cli\u003eRear flange mount with 0.5-inch MNPT connection for panel or bulkhead installation\u003c\/li\u003e\n  \u003cli\u003eGlass lens with no-fill design — no liquid fill to manage or replace\u003c\/li\u003e\n  \u003cli\u003eMeets CRN and IP66\/NEMA 4X standards for outdoor and washdown environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style process gauge for industrial pressure monitoring applications requiring a 4.5-inch rear-mount analog gauge with a 0.5-inch MNPT connection and 0 to 600 psi range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter, plumber, or industrial technician in accordance with applicable codes and the system's pressure ratings. Depressurize and isolate the process line fully before removing or installing any pressure gauge. Apply thread sealant appropriate for the process fluid to the MNPT threads — do not overtighten, as this can damage the gauge socket or process connection. Verify the gauge range is appropriate for the system's expected operating and surge pressures before placing the system back in 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: 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: 0.5 inches\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: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWetted Parts Material\u003c\/strong\u003e: Stainless Steel\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\u003eWeight\u003c\/strong\u003e: 2.5 pounds\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: 1379\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: 91548XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51539137528114,"sku":"91548XLL","price":726.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95f8bcdc83bc5f5350f7bcbd810e2402_1d0d87a2-1f50-40c4-8044-99131735f800.jpg?v=1785835227","url":"https:\/\/voomisupply.com\/products\/ashcroft-91548xll-pressure-gauge-0-600-psi-4-5-in-dial","provider":"Voomi Supply","version":"1.0","type":"link"}
