It features a 4.5-inch dial for easy readability and a rear flange mount configuration suited for panel and wall installations. Wetted parts are constructed from stainless steel, providing corrosion resistance in contact with process media. The aluminum case keeps the unit lightweight. Accuracy is rated at 0.5 percent of scale across a 0 to 1000 psi range. This gauge is installed by licensed HVAC technicians, plumbers, and pipefitters in both commercial and industrial service environments.\u003c\/p\u003e\n\u003cp\u003eThis gauge is well suited for residential and commercial mechanical systems where reliable pressure indication is needed at a stationary monitoring point. The rear flange mount allows direct panel or bulkhead mounting, keeping the face flush and readable. The 0.5-inch threaded connection accommodates standard process piping. The no-fill, dry dial design makes it appropriate for applications where liquid-filled gauges are not required or preferred. Typical install scenarios include boiler rooms, chiller skids, air compressor stations, and water distribution panels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5-inch analog dial for clear, at-a-distance pressure readings\u003c\/li\u003e\n  \u003cli\u003e0 to 1000 psi pressure range covers a wide range of mechanical system applications\u003c\/li\u003e\n  \u003cli\u003e0.5 percent of scale accuracy for reliable process monitoring\u003c\/li\u003e\n  \u003cli\u003eStainless steel wetted parts resist corrosion from process media\u003c\/li\u003e\n  \u003cli\u003eAluminum case construction reduces overall weight\u003c\/li\u003e\n  \u003cli\u003eRear flange mount enables flush panel or bulkhead installation\u003c\/li\u003e\n  \u003cli\u003eDry, no-fill dial construction requires no liquid maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style or direct replacement analog pressure gauge for use in mechanical, HVAC, plumbing, and industrial piping systems requiring a rear flange mount, 0.5-inch threaded connection, and a 4.5-inch dial format.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or HVAC technician familiar with pressure instrumentation. Depressurize and isolate the system before removing or installing any gauge. Apply thread sealant appropriate for the process media to the 0.5-inch male threads, and avoid over-tightening to prevent case or fitting damage. Verify the gauge pressure range is compatible with the system operating pressure 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 1000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.5 percent 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\u003eMount Type\u003c\/strong\u003e: Rear Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 0.5 inches\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\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\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: 91549XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51538319278386,"sku":"91549XLL","price":726.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95f8bcdc83bc5f5350f7bcbd810e2402_f5ec0d04-f67d-4d84-bf00-0b75d7014601.jpg?v=1785822886","url":"https:\/\/voomisupply.com\/products\/ashcroft-91549xll-pressure-gauge-4-5-in-dial-0-1000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
