The gauge features a 3.5-inch dial with a 0 to 1000 psi range and delivers 1% of scale accuracy, making it suitable for monitoring system pressures in HVAC, plumbing, and process piping installations. The stainless steel case and stainless steel wetted parts provide corrosion resistance in demanding environments. The lower-mount, 0.25-inch threaded connection allows direct installation into pipe taps or manifold ports. This is a dry (non-liquid-filled) gauge intended for applications where ambient vibration is not a primary concern.\u003c\/p\u003e\u003cp\u003eThis gauge is well suited for residential and light commercial mechanical systems where pressure monitoring is required on water lines, compressed air systems, or hydronic heating circuits. The lower-mount configuration positions the dial face upward for easy reading during system commissioning or routine service checks. HVAC technicians, plumbers, and pipefitters commonly install this type of gauge on boiler supply lines, pump discharge ports, or pressure test assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.5-inch analog dial for clear, at-a-glance pressure readings\u003c\/li\u003e\n\u003cli\u003e0 to 1000 psi pressure range covers a wide variety of mechanical service applications\u003c\/li\u003e\n\u003cli\u003e1% of scale accuracy for reliable system diagnostics\u003c\/li\u003e\n\u003cli\u003eStainless steel case and stainless steel wetted parts for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eLower-mount connection for direct pipe tap installation\u003c\/li\u003e\n\u003cli\u003eDry, no-fill design suitable for stable-pressure, low-vibration environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation pressure gauge for mechanical systems requiring a 0.25-inch lower-mount analog gauge with a 3.5-inch dial.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Depressurize and isolate the system before removing or installing any pressure gauge. Apply thread sealant appropriate for the service medium to the male threads before installation. Do not over-tighten; use a wrench on the hex fitting only, not on the gauge case or dial.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 1000 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: 0.25 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: 94239XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51540435697970,"sku":"94239XLL","price":226.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3bbea092f5b4780ca847ece6230fc4a_e29564b2-f80e-4dc3-b5d2-ec56182fa196.jpg?v=1785855071","url":"https:\/\/voomisupply.com\/products\/ashcroft-94239xll-pressure-gauge-3-5-in-0-1000-psi-lower-mount-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
