It features a 2.5-inch dial with a 0 to 400 psi range and delivers 1% of scale accuracy, making it suitable for applications where reliable pressure readings are required. The stainless steel case resists corrosion and physical wear in demanding service environments. Connection is via a 1\/4-inch NPT center back mount, allowing direct installation into bulkhead panels or manifold systems. Licensed HVAC technicians, plumbers, and pipefitters install this type of gauge as part of system commissioning and ongoing maintenance.\u003c\/p\u003e\n\u003cp\u003eThis gauge is well suited for residential and light commercial HVAC systems, hydronic heating loops, compressed air lines, water distribution piping, and pool or spa equipment where pressure monitoring is a routine part of service. The center back mount orientation makes it a natural fit for panel-mounted applications where a flush, forward-facing dial is needed. The non-liquid-filled design keeps the unit lightweight and straightforward to read in stable-pressure environments without significant vibration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 400 psi pressure range for high-pressure system monitoring\u003c\/li\u003e\n  \u003cli\u003e1% of scale accuracy for reliable, repeatable readings\u003c\/li\u003e\n  \u003cli\u003e2.5-inch analog dial for easy visual inspection\u003c\/li\u003e\n  \u003cli\u003eStainless steel case for corrosion resistance in wet or harsh environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPT center back mount for panel and manifold installations\u003c\/li\u003e\n  \u003cli\u003eNon-liquid-filled construction suited for stable, low-vibration applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install pressure gauge for residential and commercial systems using standard 1\/4-inch NPT center back mount fittings in HVAC, plumbing, pool, and compressed air applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or pipefitter. Shut down and depressurize the system completely before removing or installing any pressure gauge. Use thread sealant tape or compound rated for the system fluid on the NPT threads, and hand-tighten before applying a wrench to avoid over-torquing the gauge body. Follow applicable codes including the International Plumbing Code or IFGC for installation context.\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 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: 2.5 inches\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\u003eMount Type\u003c\/strong\u003e: Center Back\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 pound\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: 94893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51541650833714,"sku":"94893","price":195.48,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354cb3162489ff68ea41d248e4d39263_b2d87d47-2f06-4ced-a392-4992358d3784.jpg?v=1785881181","url":"https:\/\/voomisupply.com\/products\/ashcroft-94893-pressure-gauge-400-psi-2-5-in-npt-center-back","provider":"Voomi Supply","version":"1.0","type":"link"}
