It features a 3.5-inch dial with a 0 to 30 psi range and delivers 1% of scale accuracy, making it suitable for low-pressure system diagnostics and routine service checks. The stainless steel case provides corrosion resistance in wet or chemically active environments. The glycerin or liquid fill dampens pointer vibration, extending service life and improving readability on systems with pulsating pressure. Installed via a 1\/4-inch NPT center back mount connection, this gauge fits standard process ports found throughout residential and light commercial systems.\u003c\/p\u003e\n\u003cp\u003eThis gauge is well suited for use on water supply lines, boiler systems, hydronic heating loops, pool and spa equipment, and compressed air or gas service where pressures do not exceed 30 psi. The center back mount orientation allows for flush panel installation or direct pipe mounting where the gauge face needs to be visible straight-on. The 3.5-inch dial size provides clear readability in typical mechanical room or equipment room environments. Licensed plumbers, HVAC technicians, and pool service professionals commonly specify this gauge for both permanent installation and field service use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 30 psi pressure range suitable for low-pressure plumbing and HVAC applications\u003c\/li\u003e\n  \u003cli\u003e3.5-inch analog dial for clear, easy-to-read pressure indication\u003c\/li\u003e\n  \u003cli\u003e1% of scale accuracy for reliable diagnostic and monitoring use\u003c\/li\u003e\n  \u003cli\u003eLiquid-filled case dampens pointer vibration and extends gauge service life\u003c\/li\u003e\n  \u003cli\u003eStainless steel case resists corrosion in wet and chemically active environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPT center back mount fits standard process connections\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 residential and light commercial plumbing, HVAC, hydronic, and pool systems using standard 1\/4-inch NPT back-mount pressure ports with a maximum operating pressure of 30 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC or mechanical technician. Shut down and depressurize the system completely before removing any existing gauge or fitting the new gauge to the process connection. Apply an appropriate thread sealant to the NPT threads and hand-tighten before using a wrench to snug the connection — avoid over-torquing the stainless steel case. Verify the system pressure range does not exceed the 30 psi maximum rating of this gauge before returning the system to service.\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% of scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\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: 83195\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51542782312754,"sku":"83195","price":257.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354cb3162489ff68ea41d248e4d39263_48c65e3b-b506-40c7-8933-16f3320ba043.jpg?v=1785907298","url":"https:\/\/voomisupply.com\/products\/ashcroft-83195-pressure-gauge-30-psi-3-5-in-dial-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
