It features a 3.5-inch dial face calibrated from 0 to 400 psi, a lower-mount 1\/4-inch NPT connection, and a stainless steel case for durability in demanding environments. The gauge delivers 1% of scale accuracy, making it suitable for applications where reliable pressure readings are critical. Licensed tradespeople use this gauge to monitor system pressures on pumps, compressors, boilers, and fluid handling systems. It ships as a single unit and requires no liquid fill.\u003c\/p\u003e\u003cp\u003eThe ASHCROFT 94342 is well suited for residential and light commercial HVAC, hydronic heating, refrigeration, and general plumbing service. Its lower-mount NPT connection allows direct installation into pipe tees, manifolds, or gauge ports without additional adapters in most standard configurations. The 3.5-inch dial provides clear readability in tight mechanical spaces. HVAC technicians, plumbers, and pipefitters commonly install this gauge during system commissioning, pressure testing, and ongoing monitoring of closed-loop and open-loop systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0 to 400 psi pressure range with 1% of scale accuracy\u003c\/li\u003e\n\u003cli\u003e3.5-inch analog dial for clear, at-a-glance pressure readings\u003c\/li\u003e\n\u003cli\u003eLower-mount 1\/4-inch NPT connection for direct pipe installation\u003c\/li\u003e\n\u003cli\u003eStainless steel case for corrosion resistance in wet or harsh environments\u003c\/li\u003e\n\u003cli\u003eDry (non-liquid-filled) design for standard-duty pressure monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service gauge for systems using a standard 1\/4-inch lower-mount NPT gauge port rated to 400 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or pipefitters. Always depressurize and isolate the system before removing or installing a pressure gauge. Use thread sealant tape or pipe dope rated for the fluid type and pressure range on the NPT threads. Do not exceed the rated 400 psi maximum pressure, and verify gauge orientation matches the lower-mount configuration before tightening.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 400 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 Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Lower Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\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: 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: 1.2 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: 94342\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51538363482418,"sku":"94342","price":210.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354cb3162489ff68ea41d248e4d39263_b0f2d071-6c4a-4015-b384-1634709131ea.jpg?v=1785823763","url":"https:\/\/voomisupply.com\/products\/ashcroft-94342-pressure-gauge-400-psi-3-5-in-lower-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
