It features a 2-1\/2 inch analog dial with a 0 to 300 psi range and 1% of full-scale accuracy. The center back mount configuration with a 1\/4 inch NPT connection suits panel-mount and inline installations. The stainless steel case (grades 304 and 316) and Bourdon tube made from 316 stainless steel provide strong resistance to corrosion and mechanical stress. A polycarbonate lens protects the dial face. Licensed HVAC technicians, plumbers, and industrial pipefitters typically install this gauge on pressure systems requiring reliable, readable measurement under vibration or pulsation.\u003c\/p\u003e\n\u003cp\u003eThe ASHCROFT 83186 is suited for industrial piping, HVAC hydronic systems, compressed air lines, and fluid process equipment where a panel-ready or back-mount gauge is required. The liquid-filled design dampens needle flutter caused by system vibration or pressure spikes, improving readability and extending gauge service life. The center back mount allows clean panel installations without front-projecting connections. This gauge carries CRN, IP54, IP65\/NEMA 4, PED, and RoHS certifications, making it applicable across a range of regulated installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 300 psi pressure range with 1% of full-scale accuracy\u003c\/li\u003e\n  \u003cli\u003eLiquid-filled design reduces needle flutter from vibration and pressure pulsation\u003c\/li\u003e\n  \u003cli\u003e316 stainless steel Bourdon tube for corrosion resistance in harsh media\u003c\/li\u003e\n  \u003cli\u003eStainless steel case (grades 304 and 316) for durable, long-service-life construction\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPT center back mount for clean panel and inline installations\u003c\/li\u003e\n  \u003cli\u003eCertified to CRN, IP54, IP65\/NEMA 4, PED, and RoHS standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style industrial pressure gauge for use in hydronic, compressed air, fluid process, and general industrial piping applications requiring a 1\/4 inch NPT center back mount connection and a 2-1\/2 inch dial format.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system completely before removing any existing gauge or fitting. Apply appropriate thread sealant to the NPT connection per IPC and IFGC guidelines for the service fluid. Do not overtighten the threaded connection, as this can damage the Bourdon tube or gauge socket.\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 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1% of full scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Center Back\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBourdon Tube Material\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel (grades 304 and 316)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Polycarbonate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CRN, IP54, IP65\/NEMA 4, PED, RoHS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1009\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: 83186\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51538897404210,"sku":"83186","price":223.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d330345df2f46a921f1be0862b5d4c9.jpg?v=1785829014","url":"https:\/\/voomisupply.com\/products\/ashcroft-83186-pressure-gauge-0-300-psi-2-1-2-in-dial-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
