It features a 2.5-inch analog dial with a 0 to 30 psi range and 1 percent of scale accuracy. The Bourdon tube is constructed from 316 stainless steel, and the case is 304\/316 stainless steel, making it well-suited for corrosive or wet environments. The polycarbonate lens resists impact and moisture. A licensed plumber, HVAC technician, or industrial mechanic would typically install this gauge on pressure systems requiring precise, continuous readout with long service life.\u003c\/p\u003e\n\u003cp\u003eThis gauge is used in residential and commercial plumbing, HVAC, compressed air, hydraulic, and light industrial piping systems where continuous pressure monitoring is required. The center back mount configuration is common in panel-mounted or inline applications. The liquid-filled design dampens needle vibration caused by pressure pulsation or mechanical shock, which extends the service life of the Bourdon tube and improves readability in high-vibration environments. The 1\/4-inch NPT connection is a standard thread size compatible with a wide range of fittings and manifolds across these trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 30 psi range with 1 percent of scale accuracy for reliable pressure readings\u003c\/li\u003e\n  \u003cli\u003eLiquid-filled housing dampens needle flutter from pulsation and vibration\u003c\/li\u003e\n  \u003cli\u003e316 stainless steel Bourdon tube resists corrosion in harsh media\u003c\/li\u003e\n  \u003cli\u003e304\/316 stainless steel case for durability in wet or corrosive environments\u003c\/li\u003e\n  \u003cli\u003ePolycarbonate lens provides impact and moisture resistance\u003c\/li\u003e\n  \u003cli\u003eCenter back mount with 1\/4-inch NPT thread fits standard panel and inline installations\u003c\/li\u003e\n  \u003cli\u003eMeets 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 replacement or new-installation pressure gauge for industrial, plumbing, and HVAC pressure monitoring systems requiring a 2.5-inch dial, 0 to 30 psi range, and 1\/4-inch NPT center back mount connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or industrial mechanic. Depressurize and isolate the system fully before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads in accordance with applicable plumbing or mechanical codes. Do not over-tighten the gauge body; use the wrench flats on the fitting, not the case, to torque the connection.\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 30 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: 1\/4 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\u003eWeight\u003c\/strong\u003e: 1.5 pounds\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\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: 94903\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51543463395634,"sku":"94903","price":231.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4cc883347a349b08b56546224916344e.jpg?v=1785918985","url":"https:\/\/voomisupply.com\/products\/ashcroft-94903-pressure-gauge-0-30-psi-2-5-inch-dial-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
