It features a 4.5-inch analog dial with a 0 to 5000 psi range and an accuracy of 0.5% of scale, making it well-suited for high-pressure industrial systems. The aluminum case houses stainless steel wetted parts, providing corrosion resistance in process environments where media contact is a concern. Connection is via a 1\/2-inch MNPT rear-entry fitting, and the rear flange mount allows for direct panel or wall installation. Licensed plumbers, pipefitters, and industrial instrumentation technicians are the primary installers of this gauge.\u003c\/p\u003e\u003cp\u003eThis gauge is intended for process and industrial applications where reliable pressure indication at elevated ranges is required. Its no-fill, dry design suits environments where liquid-filled gauges are not appropriate or preferred. The NEMA 4X and IP66 ratings make it suitable for outdoor installations or areas subject to washdown and moisture exposure. The glass lens and analog dial provide clear local indication without the need for external power or signal conditioning.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.5-inch analog dial with 0 to 5000 psi range for high-pressure process monitoring\u003c\/li\u003e\n\u003cli\u003e0.5% of scale accuracy for reliable process indication\u003c\/li\u003e\n\u003cli\u003eStainless steel wetted parts resist corrosion from aggressive media\u003c\/li\u003e\n\u003cli\u003eAluminum case keeps weight manageable while providing structural durability\u003c\/li\u003e\n\u003cli\u003eRear flange mount with 1\/2-inch MNPT connection for direct panel installation\u003c\/li\u003e\n\u003cli\u003eIP66 and NEMA 4X rated for outdoor and washdown environments\u003c\/li\u003e\n\u003cli\u003eNo-fill dry gauge design eliminates concerns about liquid filler contamination\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style process gauge for industrial piping systems, pressure vessels, and fluid handling equipment requiring a 1\/2-inch MNPT rear-mount connection and a 4.5-inch dial format.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pipefitter or instrumentation technician. Isolate and depressurize the system completely before removing any existing gauge or fitting. Apply thread sealant appropriate for the process media to the MNPT threads, and do not overtighten, as this can crack the gauge socket. Verify gauge range is appropriate for the system's expected operating and surge pressures before placing into service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 5000 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\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.5 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: 91554XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51543031284018,"sku":"91554XLL","price":801.62,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95f8bcdc83bc5f5350f7bcbd810e2402_c4374477-9c8c-4338-8815-a55e9612d95e.jpg?v=1785914159","url":"https:\/\/voomisupply.com\/products\/ashcroft-91554xll-pressure-gauge-4-5-in-0-5000-psi-rear-flange","provider":"Voomi Supply","version":"1.0","type":"link"}
