It features a 3.5-inch dial with a 0 to 100 psi range and an accuracy rating of 3-2-3 percent of scale, meaning the middle 94 percent of the range reads within 2 percent and the outer spans read within 3 percent. The steel case protects the internals in light mechanical environments, while the polycarbonate lens resists impact and holds up to typical shop conditions. A 1\/4-inch NPT center back mount connection makes installation straightforward on standard gauge ports found in most commercial and residential mechanical systems. Licensed tradespeople in HVAC and plumbing install this gauge as a permanent monitoring instrument or as a service replacement.\u003c\/p\u003e\n\u003cp\u003eThis gauge is suited for residential and light commercial applications where a reliable, easy-to-read dial instrument is needed to monitor water pressure, air pressure, or similar non-corrosive media. The 3.5-inch dial face is large enough for quick visual checks at arm's length on boiler supply lines, chilled water circuits, compressed air manifolds, and similar service points. The center back mount orientation allows flush or panel mounting in tight equipment rooms. The bronze Bourdon tube is compatible with water, air, and many common non-aggressive fluids encountered in mechanical systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 100 psi range with 3-2-3 percent of scale accuracy for reliable mid-range readings\u003c\/li\u003e\n  \u003cli\u003e3.5-inch analog dial for clear at-a-glance pressure monitoring\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPT center back mount connection fits standard gauge ports\u003c\/li\u003e\n  \u003cli\u003eSteel case construction for durability in commercial mechanical environments\u003c\/li\u003e\n  \u003cli\u003eBronze Bourdon tube compatible with water, air, and non-aggressive media\u003c\/li\u003e\n  \u003cli\u003ePolycarbonate lens resists impact and provides a clear view of the dial face\u003c\/li\u003e\n  \u003cli\u003eCRN certified for use in applicable Canadian pressure system applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit commercial pressure gauge replacement for systems requiring a 1\/4-inch NPT center back mount port and a 0 to 100 psi analog dial instrument.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or pipefitter in accordance with applicable local mechanical codes. Always depressurize and isolate the system before removing or installing any pressure gauge. Use an appropriate thread sealant or PTFE tape on the NPT threads and hand-tighten before applying final torque with an adjustable wrench on the hex fitting only — do not torque by gripping the case. Verify the gauge orientation after installation so the dial face remains readable during normal system operation.\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 100 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 3-2-3 percent 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\u003eThread Size and Type\u003c\/strong\u003e: 1\/4-inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Center Back\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBourdon Tube Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Polycarbonate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CRN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1001T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 662876143030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51542957785394,"sku":"662876143030","price":89.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f007ca396638e739045b751d5754dc4.jpg?v=1785912173","url":"https:\/\/voomisupply.com\/products\/ashcroft-662876143030-pressure-gauge-0-100-psi-3-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
