It features a 4.5-inch dial with a measurement range of 0 to 800 psi and delivers accuracy rated at 0.5 percent of scale. The case is constructed from thermoplastic, keeping the unit lightweight without sacrificing durability. This is a dry (no-fill) gauge, making it suited for applications where fluid contamination is not acceptable. The rear flange mount design simplifies panel or wall installation. HVAC technicians, plumbers, and mechanical contractors use gauges like this for system diagnostics, pressure testing, and permanent monitoring installations.\u003c\/p\u003e\u003cp\u003eThis gauge is appropriate for residential and commercial mechanical systems where a large, easy-to-read 4.5-inch dial is needed. The rear flange mount is commonly used in panel-mounted configurations where the gauge face must be flush with or recessed into a surface. The 0.5-inch threaded connection provides a standard, secure attachment point to process lines or test ports. It is not liquid filled, so it performs best in environments with low vibration and minimal pressure pulsation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.5-inch analog dial for clear, at-a-distance pressure readings\u003c\/li\u003e\n\u003cli\u003e0 to 800 psi measurement range suitable for a wide range of medium- to high-pressure applications\u003c\/li\u003e\n\u003cli\u003e0.5 percent of scale accuracy for reliable system monitoring\u003c\/li\u003e\n\u003cli\u003eDry (no-fill) construction avoids fluid contamination in sensitive environments\u003c\/li\u003e\n\u003cli\u003eRear flange mount for clean panel and surface installations\u003c\/li\u003e\n\u003cli\u003eThermoplastic case reduces weight while providing adequate protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard rear-flange-mount analog pressure gauge suitable for panel installations in HVAC, plumbing, and general mechanical piping systems with process connections requiring a 0.5-inch threaded fitting.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed technician or qualified mechanical contractor. Depressurize and isolate the system completely before removing any existing gauge or making connections. Apply appropriate thread sealant to the 0.5-inch threaded connection per the system manufacturers recommendations and applicable plumbing or mechanical codes. Because this is a dry gauge, avoid installing it on lines with severe pulsation or vibration, which can shorten service life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 800 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 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\u003eLiquid Filled\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Thermoplastic\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: 80100XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51542272704818,"sku":"80100XLL","price":391.58,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/760f8efc512ec2bc85a40aae2d63044d_78171833-ec0a-4b56-bc86-feb74d477fbf.jpg?v=1785897023","url":"https:\/\/voomisupply.com\/products\/ashcroft-80100xll-pressure-gauge-4-5-in-dial-800-psi-rear-flange","provider":"Voomi Supply","version":"1.0","type":"link"}
