It features a 2.5-inch analog dial with a 0 to 400 psi range and a 1-percent-of-scale accuracy rating. The gauge uses a 316 stainless steel Bourdon tube as the sensing element and is housed in a 304\/316 stainless steel case with a polycarbonate lens. Liquid filling dampens pointer vibration and protects internal components in high-pulsation or high-vibration environments. Licensed plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals are the typical installers.\u003c\/p\u003e\u003cp\u003eThis gauge is suited for residential and commercial applications involving water, oil, gas, and compatible fluid systems where a back-mount configuration is required. The center back mount and 0.25-inch NPT male connection allow direct installation into pipelines, manifolds, or process equipment panels. The stainless steel construction makes it appropriate for mildly corrosive or washdown environments. The liquid-filled design is especially useful in pump discharge, compressed air, and hydraulic monitoring applications where pressure pulsations are common.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0 to 400 psi range with 1-percent-of-scale accuracy for reliable process monitoring\u003c\/li\u003e\n\u003cli\u003e316 stainless steel Bourdon tube resists corrosion in demanding fluid and gas service\u003c\/li\u003e\n\u003cli\u003e304\/316 stainless steel case with polycarbonate lens for durability in washdown-rated environments\u003c\/li\u003e\n\u003cli\u003eLiquid-filled design dampens vibration and protects movement from pulsation and pressure spikes\u003c\/li\u003e\n\u003cli\u003eCenter back mount with 0.25-inch NPT thread for straightforward panel or pipeline installation\u003c\/li\u003e\n\u003cli\u003eMeets CRN, IP54, IP65\/NEMA 4, PED, and RoHS standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install industrial pressure gauge for systems requiring a 0.25-inch NPT center back mount connection and a 0 to 400 psi analog gauge in a 2.5-inch dial format.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Depressurize and isolate the system completely before removing any existing gauge or fitting the new gauge into the port. Apply appropriate thread sealant to the NPT threads per local code requirements, and do not over-tighten, as stainless fittings can gall. Verify that the process fluid is compatible with stainless steel wetted parts before placing the gauge in service.\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 percent of scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.5 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: Center Back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 0.25 inches NPT\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: 304\/316 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Polycarbonate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 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: 83187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51542908502322,"sku":"83187","price":223.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1a66614a267ecb455b3bad8d45ea5c2.jpg?v=1785910575","url":"https:\/\/voomisupply.com\/products\/ashcroft-83187-pressure-gauge-0-400-psi-2-5-in-dial-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
