It features a 3.5-inch dial face with a 0 to 15 psi range and delivers 1 percent of scale accuracy, making it suitable for low-pressure applications where reliable readings are required. The stainless steel case provides corrosion resistance in demanding service environments. The 1\/4-inch NPT center back mount configuration allows direct inline installation into piping systems. This gauge is a standard tool-of-the-trade for HVAC technicians, plumbers, pipefitters, and industrial service professionals who need dependable analog pressure indication.\u003c\/p\u003e\u003cp\u003eThe ASHCROFT 83189 is appropriate for residential and light commercial plumbing, HVAC hydronic systems, compressed air lines, and process piping where pressures remain at or below 15 psi. The center back mount orientation suits panel-mounted or direct-pipe installations where the gauge face needs to be visible from the front. The dry, non-liquid-filled construction keeps the design straightforward for standard ambient temperature applications without the need for glycerin fill dampening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0 to 15 psi pressure range for low-pressure system monitoring\u003c\/li\u003e\n\u003cli\u003e3.5-inch analog dial for clear, at-a-glance readings\u003c\/li\u003e\n\u003cli\u003e1 percent of scale accuracy for reliable pressure indication\u003c\/li\u003e\n\u003cli\u003eStainless steel case offers corrosion resistance in wet or harsh environments\u003c\/li\u003e\n\u003cli\u003e1\/4-inch NPT center back mount for direct pipe or panel installation\u003c\/li\u003e\n\u003cli\u003eDry gauge construction — no liquid fill, simplified maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new-installation analog pressure gauge for 1\/4-inch NPT center back mount applications in plumbing, HVAC hydronic, and light process piping systems operating at or below 15 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and ASME B40.100 guidelines for pressure gauge installation. Depressurize and isolate the system completely before removing any existing gauge or making new connections. Apply thread sealant tape or compound to the NPT threads before installation — do not overtighten, as stainless steel fittings can gall. Verify the system operating pressure does not exceed the gauge maximum range of 15 psi.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 15 psi\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\u003eAccuracy\u003c\/strong\u003e: 1 percent of scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Center Back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 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: 83189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51538336284978,"sku":"83189","price":239.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354cb3162489ff68ea41d248e4d39263_3a212fba-7534-4773-a7b9-740045af7f98.jpg?v=1785823190","url":"https:\/\/voomisupply.com\/products\/ashcroft-83189-pressure-gauge-15-psi-3-5-in-dial-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
