Featuring a 4.5-inch dial for easy readout, this gauge covers a range of 0 to 300 psi with an accuracy of 0.5% of scale. The aluminum case keeps weight low while the stainless steel wetted parts resist corrosion in demanding fluid and gas service environments. Installed via a rear flange mount with a 1\/4-inch thread connection, it suits panel-mount and surface-mount applications where the gauge face must align flush with a surface. HVAC technicians, plumbers, and mechanical contractors are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis gauge is appropriate for residential and commercial applications where a mid-range pressure measurement point is needed. Typical install scenarios include boiler systems, compressed air lines, water supply monitoring, and HVAC hydronic loops. The 4.5-inch dial is well-suited for installations requiring clear remote readability from a distance. The non-liquid-filled design keeps the gauge lightweight and clean for dry-service environments where vibration is not a primary concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5-inch analog dial provides clear, easy-to-read pressure indication\u003c\/li\u003e\n  \u003cli\u003e0 to 300 psi pressure range suits a wide variety of mechanical and HVAC applications\u003c\/li\u003e\n  \u003cli\u003e0.5% of scale accuracy for precise pressure monitoring\u003c\/li\u003e\n  \u003cli\u003eStainless steel wetted parts offer corrosion resistance in fluid and gas service\u003c\/li\u003e\n  \u003cli\u003eAluminum case reduces overall weight without sacrificing durability\u003c\/li\u003e\n  \u003cli\u003eRear flange mount design allows flush panel or surface installation\u003c\/li\u003e\n  \u003cli\u003eNon-liquid-filled construction for clean, dry-service environments\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 systems requiring a 1\/4-inch rear-threaded, rear-flange-mount analog gauge in the 0 to 300 psi range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor in accordance with applicable local codes. Isolate and depressurize the system fully before removing or installing any pressure gauge. Apply appropriate thread sealant to the 1\/4-inch male thread connection and tighten to snug-plus-quarter-turn by hand before final wrench tightening — avoid over-torquing, which can crack the socket or distort the case. Do not install this gauge in applications with significant vibration or pulsation without an inline snubber or dampener.\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 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.5% 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: Rear Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 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: 93753XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51539554861362,"sku":"93753XLL","price":726.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95f8bcdc83bc5f5350f7bcbd810e2402_78fa371a-3ec9-45b8-8d8e-bda0f3914ce3.jpg?v=1785842975","url":"https:\/\/voomisupply.com\/products\/ashcroft-93753xll-pressure-gauge-4-5-in-dial-rear-flange","provider":"Voomi Supply","version":"1.0","type":"link"}
