The 3.5-inch dial provides a clear read from a distance, and the lower-mount, 1\/4-inch threaded connection makes inline installation straightforward. The stainless steel case and stainless steel wetted parts deliver corrosion resistance in demanding environments. Accuracy is rated at 1% of scale, meeting general industrial and mechanical service requirements. This gauge ships dry with no liquid fill. Licensed HVAC technicians, plumbers, and mechanical contractors commonly use this style of gauge for system pressure monitoring and service diagnostics.\u003c\/p\u003e\u003cp\u003eThis gauge is suited for residential and light commercial applications where a compact, durable compound gauge is needed on hydronic heating systems, refrigeration circuits, compressed air lines, water supply systems, or other fluid-handling equipment. The lower-mount configuration allows the gauge to thread directly into a tee, valve, or manifold with the dial face pointing up or outward for easy viewing during service.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompound pressure range: 30 inches vacuum to 0 to 300 psi\u003c\/li\u003e\n\u003cli\u003e3.5-inch analog dial for clear, distance-readable display\u003c\/li\u003e\n\u003cli\u003eStainless steel case and stainless steel wetted parts for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e1% of scale accuracy for reliable pressure readings\u003c\/li\u003e\n\u003cli\u003eLower-mount, 1\/4-inch threaded connection for direct inline installation\u003c\/li\u003e\n\u003cli\u003eDry gauge — no liquid fill\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or new-installation pressure gauge for systems using a 1\/4-inch lower-mount threaded port in HVAC, plumbing, and mechanical service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. Isolate and depressurize the system completely before threading the gauge into the port. Use appropriate thread sealant or PTFE tape on the male threads and tighten with a wrench on the gauge hex — do not apply torque to the case body. Verify the system pressure range falls within the gauge rating before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 30 inches vacuum to 0 to 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1% of scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 3.5 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: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel\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: 0.25 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: 83224XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51541846622514,"sku":"83224XLL","price":335.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3bbea092f5b4780ca847ece6230fc4a_6f33b1b6-b27f-4655-b689-faafe0f8d541.jpg?v=1785886666","url":"https:\/\/voomisupply.com\/products\/ashcroft-83224xll-pressure-gauge-3-5in-lower-mount-30-0-300-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
