It features a 4.5-inch analog dial with a 0 to 100 psi range and delivers an accuracy of 0.5 percent of scale, making it suitable for precision pressure monitoring in process systems. The case is aluminum with stainless steel wetted parts for corrosion resistance, and the lens is glass. The gauge is no-fill (dry) type and mounts via a rear flange with a 0.5-inch MNPT connection. Licensed HVAC techs, pipefitters, plumbers, and industrial maintenance professionals install this gauge in process piping and equipment panels.\u003c\/p\u003e\n\u003cp\u003eThe 91543XLL is suited for process piping systems in residential, commercial, and light industrial environments where accurate pressure readings are required at panel-mount or rear-flange locations. The rear flange mount integrates cleanly into control panels or bulkhead installations. Its stainless steel wetted parts make it appropriate for mildly corrosive media, and the glass lens and aluminum case hold up under standard process conditions. The gauge carries CRN certification and meets IP66 and NEMA 4X ingress protection ratings, qualifying it for wet or washdown environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5-inch analog dial for easy reading at distance\u003c\/li\u003e\n  \u003cli\u003e0 to 100 psi range with 0.5 percent of scale accuracy\u003c\/li\u003e\n  \u003cli\u003eStainless steel wetted parts for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eAluminum case with glass lens\u003c\/li\u003e\n  \u003cli\u003eRear flange mount with 0.5-inch MNPT connection\u003c\/li\u003e\n  \u003cli\u003eDry (no-fill) construction — no liquid filler\u003c\/li\u003e\n  \u003cli\u003eIP66 and NEMA 4X rated for washdown and outdoor environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style process pressure gauge for use in industrial and commercial process piping systems requiring a rear flange mount, 0.5-inch MNPT connection, and a 4.5-inch dial format.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, pipefitters, or industrial maintenance technicians. Isolate and depressurize the system completely before removing or installing the gauge. Apply appropriate thread sealant to the MNPT connection per the piping system requirements and applicable plumbing or process codes. Do not overtighten the threaded connection, as this can damage the gauge socket or process fitting.\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 100 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\u003eThread Size\u003c\/strong\u003e: 0.5 inches MNPT\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\u003eCertifications\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: 91543XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51541516124466,"sku":"91543XLL","price":726.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95f8bcdc83bc5f5350f7bcbd810e2402_81361730-5bc6-4e71-acfa-5fd17d2e6122.jpg?v=1785878065","url":"https:\/\/voomisupply.com\/products\/ashcroft-91543xll-pressure-gauge-0-100-psi-4-5-in-dial","provider":"Voomi Supply","version":"1.0","type":"link"}
