It features a 2.5-inch dial face and reads from -30 Hg to 0, making it suitable for vacuum measurement applications in HVAC, plumbing, and industrial service environments. The gauge mounts via a 1\/4-inch NPT center back connection and is housed in a steel case for durability in field and shop conditions. Licensed HVAC technicians and plumbers typically install this gauge for system evacuation monitoring, line testing, and pressure diagnostics where vacuum readings are required.\u003c\/p\u003e\n\u003cp\u003eThis gauge is suited for residential and light commercial applications where vacuum pressure monitoring is part of routine system service. Common installation scenarios include refrigeration system evacuation verification, plumbing vacuum testing, and process line diagnostics. The center back mount configuration allows the gauge to sit flush against panels or manifolds, keeping the dial face forward-facing for easy reading. Its compact 2.5-inch dial provides clear analog readout without requiring digital instrumentation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAnalog dial reads -30 Hg to 0 for vacuum pressure measurement\u003c\/li\u003e\n  \u003cli\u003e2.5-inch dial diameter for clear, direct readout\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPT center back mount for panel or manifold installation\u003c\/li\u003e\n  \u003cli\u003eSteel case construction for durability in field service conditions\u003c\/li\u003e\n  \u003cli\u003eCompact form factor fits tight equipment spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service gauge for systems requiring 1\/4-inch NPT center back mount vacuum gauges with a 2.5-inch dial face.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or plumber. Isolate and depressurize the system fully before connecting or disconnecting any gauge. Apply thread sealant rated for the service media to the NPT threads and tighten to the fitting using an appropriately sized wrench — do not over-tighten. Verify the pressure range of the gauge is compatible with the system being tested before placing the gauge in service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: -30 Hg to 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\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\u003eCase Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 662876001415\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51541783183666,"sku":"662876001415","price":64.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312b3539fc764dd3482b1c7a0f354a61.jpg?v=1785884790","url":"https:\/\/voomisupply.com\/products\/ashcroft-662876001415-vacuum-pressure-gauge-2-5-in-dial-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
