It features a 4.5-inch dial for easy readout at a distance, a 1\/4-inch center back mount connection, and a measurement range of 30 inches of vacuum to 100 psi. The aluminum case keeps weight low while bronze wetted parts provide corrosion resistance in contact with the process media. Accuracy is rated at 0.5 percent of scale, making it suitable for general process monitoring, HVAC systems, plumbing, and mechanical utility applications. A licensed HVAC technician, plumber, or industrial mechanic typically installs this gauge.\u003c\/p\u003e\n\u003cp\u003eThis pressure gauge is suited for use in residential, commercial, and light industrial environments. Its no-fill, non-liquid-filled design simplifies installation and maintenance compared to glycerin-filled gauges. The center back mount configuration is commonly used in panel-mount and pipe-mount installations where the gauge face needs to be flush or recessed. The 4.5-inch dial size is standard for systems where multiple gauges are monitored from a control panel or equipment room. Applications include boiler systems, compressed air lines, water supply systems, hydronic heating circuits, and HVAC refrigeration monitoring at gauge ports.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5-inch analog dial for clear, long-distance pressure readout\u003c\/li\u003e\n  \u003cli\u003ePressure range: 30 inches vacuum to 100 psi (compound range)\u003c\/li\u003e\n  \u003cli\u003e0.5 percent of scale accuracy for reliable general-service measurement\u003c\/li\u003e\n  \u003cli\u003eBronze wetted parts resist corrosion in contact with process media\u003c\/li\u003e\n  \u003cli\u003eAluminum case reduces overall weight\u003c\/li\u003e\n  \u003cli\u003eNo-fill design requires no glycerin or liquid maintenance\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch center back mount connection fits standard gauge ports\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install pressure gauge for general industrial, HVAC, plumbing, and mechanical systems using a 1\/4-inch center back mount connection with a compound pressure range up to 100 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or mechanical contractor. Depressurize and isolate the system fully before removing an existing gauge or installing this unit. Apply thread sealant or PTFE tape to the 1\/4-inch male threads per local plumbing code requirements; do not overtighten, as aluminum and brass gauge bodies can crack. Verify that the system operating pressure falls within the gauge range before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 30 inches vacuum to 100 psi\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\u003eAccuracy\u003c\/strong\u003e: 0.5 percent of scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Center Back\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\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: Bronze\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: 80297XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51538537316658,"sku":"80297XLL","price":565.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2520c894981d737d69c5eca388ab384_0af40e4f-7012-4c2a-9852-175d68b43867.jpg?v=1785824982","url":"https:\/\/voomisupply.com\/products\/ashcroft-80297xll-pressure-gauge-4-5-in-dial-0-100-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
