It features a stainless steel case and bronze wetted parts, making it suitable for use with a range of compatible media. The gauge reads a compound range of 30 inches Hg vacuum to 0 to 100 psi, giving technicians visibility into both negative and positive pressure in a single instrument. Accuracy is rated at 1 percent of scale. The 1\/4-inch center back mount configuration allows for direct panel or pipe installation. No liquid fill is used, keeping the gauge lightweight at 0.25 pounds.\u003c\/p\u003e\n\u003cp\u003eThis gauge is appropriate for HVAC, plumbing, refrigeration, and light industrial applications where a compact, readable pressure indicator is required. The center back mount is a common configuration for panel-mounted instrumentation and inline service points. Licensed HVAC technicians and plumbers routinely install this type of gauge on suction lines, supply lines, and manifold assemblies where compound pressure readings are needed. The dry (no-fill) design suits environments where vibration is not a primary concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompound pressure range: 30 inches Hg vacuum to 0 to 100 psi on a single dial\u003c\/li\u003e\n  \u003cli\u003e1 percent of scale accuracy for reliable field readings\u003c\/li\u003e\n  \u003cli\u003eStainless steel case for corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003eBronze wetted parts compatible with common system media\u003c\/li\u003e\n  \u003cli\u003e2.5-inch analog dial provides clear, at-a-glance readability\u003c\/li\u003e\n  \u003cli\u003eNo-fill design — lightweight and straightforward to service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install compound pressure gauge for HVAC, plumbing, and light industrial systems requiring a 1\/4-inch center back mount configuration with a 2.5-inch dial.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with applicable local codes. Always depressurize and isolate the system before removing or installing a pressure gauge. Apply an appropriate thread sealant to the 1\/4-inch NPT connection and tighten to the fitting without over-torquing the case. Verify that the pressure range of the gauge does not exceed the system operating pressure 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: 30 inches Hg to 0 to 100 psi (compound)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1 percent 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: 2.5 inches\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\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWetted Parts Material\u003c\/strong\u003e: Bronze\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: 0.25 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: 81378XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51544606048562,"sku":"81378XLL","price":203.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3bbea092f5b4780ca847ece6230fc4a_660e0500-41f5-40fc-bc76-4eeb7dbc4d42.jpg?v=1785931249","url":"https:\/\/voomisupply.com\/products\/ashcroft-81378xll-pressure-gauge-2-5-in-dial-30-0-100-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
