It features a 4.5-inch dial for easy reading at a distance and a lower-mount 0.5-inch threaded connection for direct inline or panel installation. The aluminum case keeps weight low while the stainless steel wetted parts resist corrosion in demanding service environments. Accuracy is rated at 0.5 percent of scale, making it suitable for processes where reliable pressure indication is critical. This gauge ships dry with no liquid fill, which simplifies installation in temperature-stable environments. Licensed HVAC technicians, pipefitters, and industrial mechanics are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis gauge is suited for high-pressure hydraulic systems, compressed gas lines, water treatment equipment, and industrial process piping where a durable, readable pressure indicator is required. The 4.5-inch dial size is commonly specified in commercial and industrial settings where readability from a distance is a priority. The lower-mount configuration allows direct connection to pipe fittings or manifolds with the dial face oriented upward for clear line-of-sight reading.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-range measurement: 0 to 20000 psi pressure range\u003c\/li\u003e\n  \u003cli\u003e4.5-inch analog dial for clear readability at a distance\u003c\/li\u003e\n  \u003cli\u003e0.5 percent of scale accuracy for reliable process indication\u003c\/li\u003e\n  \u003cli\u003eStainless steel wetted parts for corrosion resistance in aggressive media\u003c\/li\u003e\n  \u003cli\u003eAluminum case reduces overall gauge weight\u003c\/li\u003e\n  \u003cli\u003eDry, no-fill design simplifies installation in stable temperature environments\u003c\/li\u003e\n  \u003cli\u003eLower-mount 0.5-inch threaded connection for direct pipe or manifold attachment\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 industrial process systems, hydraulic equipment, and compressed gas applications requiring a lower-mount, 0.5-inch threaded gauge with a 4.5-inch dial and a 0 to 20000 psi range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed pipefitter, industrial mechanic, or qualified technician familiar with high-pressure system service. Always depressurize and isolate the system before removing or installing any pressure gauge. Apply thread sealant or PTFE tape appropriate for the system media and pressure rating before threading the gauge into the fitting. Verify the gauge pressure range is compatible with the system's maximum operating pressure before commissioning.\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 20000 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: Lower\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: 451379S4LXLL20K\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51540602847538,"sku":"451379S4LXLL20K","price":1194.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95f8bcdc83bc5f5350f7bcbd810e2402_568a9ee1-471c-4c2c-96ec-42fd8be1c796.jpg?v=1785859751","url":"https:\/\/voomisupply.com\/products\/ashcroft-451379s4lxll20k-pressure-gauge-4-5-in-20000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
