It features an 8.5-inch aluminum case dial with a measurement range of 0 to 400 psi and a glass lens for clear readability. The gauge uses a bronze Bourdon tube internally and connects via a 0.25-inch NPT lower-mount fitting. Accuracy is rated at 0.25 percent of scale, making it suitable for applications where reliable pressure readings are critical. Licensed HVAC technicians, plumbers, and pipefitters commonly specify this gauge for high-visibility panel and pipe installations.\u003c\/p\u003e\u003cp\u003eThis gauge is well suited for use in commercial HVAC systems, plumbing distribution lines, compressed air systems, and industrial process piping where a large-dial, lower-mount configuration is required. The 8.5-inch dial size allows easy reading at a distance, making it a practical choice for equipment rooms, boiler rooms, and mechanical skids. The lower-mount NPT connection simplifies installation on vertical pipe runs and manifold blocks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8.5-inch aluminum case dial for high-visibility pressure reading\u003c\/li\u003e\n\u003cli\u003e0 to 400 psi range with 0.25 percent of scale accuracy\u003c\/li\u003e\n\u003cli\u003eBronze Bourdon tube construction for reliable pressure sensing\u003c\/li\u003e\n\u003cli\u003e0.25-inch NPT lower-mount connection for vertical pipe installation\u003c\/li\u003e\n\u003cli\u003eGlass lens for clear, durable dial protection\u003c\/li\u003e\n\u003cli\u003eCRN certified for use in applicable jurisdictions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit analog pressure gauge for systems requiring a lower-mount, 0.25-inch NPT connection with an 8.5-inch dial and a 0 to 400 psi measurement range.

Shut off and depressurize the system fully before removing or installing any pressure gauge. Use appropriate thread sealant on NPT connections and avoid overtightening, which can damage the gauge body or fitting. Confirm the system operating pressure falls within the 0 to 400 psi rated range before commissioning.\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: 0.25 percent of scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 8.5 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\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBourdon Tube Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CRN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7 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: 86466\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51542778347826,"sku":"86466","price":1780.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/180bb9faa0748d66c7dcfbb71cd71c49_1c55bff3-356a-418b-b7fa-379eb060511d.jpg?v=1785907152","url":"https:\/\/voomisupply.com\/products\/ashcroft-86466-pressure-gauge-0-400-psi-8-5-in-dial-lower-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
