It features a 3.5-inch analog dial with a 0 to 160 psi range and a 1% of scale accuracy rating. The gauge mounts via a 1\/4-inch NPT center back connection, making it straightforward to install inline or on pressure ports in piping systems. The stainless steel case and 316 stainless steel Bourdon tube provide corrosion resistance in wet, chemical-exposed, or harsh environments. The polycarbonate lens protects the dial face while maintaining readability. Licensed HVAC, plumbing, and industrial service technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis gauge is well suited for residential and commercial HVAC systems, plumbing pressure monitoring, hydraulic circuits, and general industrial fluid systems where a rugged, liquid-filled gauge is required. The liquid fill dampens needle vibration in high-pulsation applications, extending gauge service life and improving readability under dynamic conditions. The center back mount orientation suits panel-mounted and direct pipe-tapped installations where a flush or recessed gauge face is preferred.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLiquid-filled construction dampens needle vibration in pulsating flow applications\u003c\/li\u003e\n\u003cli\u003e316 stainless steel Bourdon tube resists corrosion in aggressive media\u003c\/li\u003e\n\u003cli\u003e304 and 316 stainless steel case for long-term durability in harsh environments\u003c\/li\u003e\n\u003cli\u003e1% of scale accuracy across the full 0 to 160 psi range\u003c\/li\u003e\n\u003cli\u003ePolycarbonate lens protects the analog dial face\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 or aftermarket replacement industrial pressure gauge for systems requiring a 3.5-inch dial, 1\/4-inch NPT center back mount, 0 to 160 psi range gauge in HVAC, plumbing, or industrial piping applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified industrial pipefitter familiar with pressure instrumentation. Shut off system pressure and depressurize the line completely before removing an existing gauge or installing this unit. Apply thread sealant or PTFE tape to the NPT threads in accordance with applicable plumbing codes before making up the connection. Do not over-tighten the threaded connection, as this may damage the gauge socket or fitting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge Type\u003c\/strong\u003e: Industrial Pressure Gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 160 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 Diameter\u003c\/strong\u003e: 3.5 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 and Type\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: Stainless Steel (304\/316)\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\u003eSeries\u003c\/strong\u003e: 1009\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\u003eWeight\u003c\/strong\u003e: 2 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: 83198\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51538991153458,"sku":"83198","price":248.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3e422dac115ade6b14222af980eb3cc.jpg?v=1785832032","url":"https:\/\/voomisupply.com\/products\/ashcroft-83198-pressure-gauge-0-160-psi-3-5in-dial-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
