It features a 4.5-inch dial for easy readability at a distance and a 0 to 100 psi measurement range. The thermoplastic case provides resistance to corrosive environments, and the glass lens offers durable, clear viewing. Accuracy is rated at 0.5 percent of scale, meeting the precision demands of process systems. The gauge mounts via a rear flange configuration with a 1\/4-inch MNPT threaded connection and is a dry, no-fill unit. Licensed HVAC technicians, plumbers, and industrial pipe fitters are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis gauge is suited for process piping, HVAC systems, plumbing distribution, and light industrial fluid systems where a panel-mounted or rear-flange-mounted pressure indicator is needed. The rear flange mount allows the gauge to be surface-mounted against a panel or wall while the connection threads into the process line from behind. The 4.5-inch dial size is well suited for control panels and equipment rooms where at-a-glance readings are important. The no-fill design keeps installation straightforward with no concern for liquid filler compatibility with the process media.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 100 psi pressure range with 0.5 percent of scale accuracy\u003c\/li\u003e\n  \u003cli\u003e4.5-inch analog dial for high visibility in panel or wall-mount applications\u003c\/li\u003e\n  \u003cli\u003eThermoplastic case rated to IP66 and NEMA 4X for washdown and corrosive environments\u003c\/li\u003e\n  \u003cli\u003eRear flange mount configuration for surface or panel installation\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch MNPT threaded process connection\u003c\/li\u003e\n  \u003cli\u003eDry, no-fill construction simplifies installation and media compatibility\u003c\/li\u003e\n  \u003cli\u003eMeets CRN certification requirements\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, commercial HVAC, and plumbing systems requiring a rear flange mount with a 1\/4-inch MNPT connection and a 0 to 100 psi range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and ASME B40.100 pressure gauge standards. Shut off and depressurize the system completely before threading the gauge into the process connection. Apply appropriate thread sealant to the MNPT connection and hand-tighten before using a wrench to avoid cracking the thermoplastic case. Do not overtighten, and verify the system is fully pressurized before relying on the gauge reading for process decisions.\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: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: 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: Thermoplastic\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\u003eSeries\u003c\/strong\u003e: 1279\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CRN, IP66, NEMA 4X\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: 451279AS02LXLL100#\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51538786615602,"sku":"451279AS02LXLL100#","price":331.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/760f8efc512ec2bc85a40aae2d63044d_91059799-553e-4fbc-9d11-2c6c7b26f73c.jpg?v=1785826544","url":"https:\/\/voomisupply.com\/products\/ashcroft-451279as02lxll100-pressure-gauge-0-100-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
