The gauge features a 4.5-inch aluminum case dial, stainless steel wetted parts, and a rear flange mount configuration. It covers a compound pressure range of 30 to 0 to 30 psi, making it suitable for systems that require both vacuum and positive pressure readings. Accuracy is rated at 0.5% of scale. This gauge is installed by licensed plumbers, HVAC technicians, and mechanical contractors in process piping, HVAC systems, and utility mechanical rooms.\u003c\/p\u003e\n\u003cp\u003eThis gauge is well suited for residential and commercial mechanical applications where a rear flange mount is needed for panel or wall-mounted installations. The compound range supports use on systems where pressure can swing below atmospheric, such as suction lines, vacuum systems, or hydronic loops. The 0.5-inch thread connection provides a standard fitting interface. The gauge ships dry with no liquid fill, keeping it compatible with environments where fluid contamination or freezing of fill media is a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompound pressure range: 30 to 0 to 30 psi for vacuum and positive pressure monitoring\u003c\/li\u003e\n  \u003cli\u003e4.5-inch analog dial for easy reading at distance\u003c\/li\u003e\n  \u003cli\u003eStainless steel wetted parts for corrosion resistance in demanding service\u003c\/li\u003e\n  \u003cli\u003eAluminum case construction reduces overall weight\u003c\/li\u003e\n  \u003cli\u003eRear flange mount for secure panel or surface mounting\u003c\/li\u003e\n  \u003cli\u003eNo liquid fill — avoids freeze damage and fill fluid contamination concerns\u003c\/li\u003e\n  \u003cli\u003e0.5% of scale accuracy for reliable readings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct installation gauge for mechanical piping systems requiring a rear flange mount, 0.5-inch threaded connection, and 4.5-inch dial in compound psi service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified plumber, HVAC technician, or industrial pipefitter. Isolate and depressurize the system fully before removing any existing gauge or fittings. Apply appropriate thread sealant to the male threads per local plumbing code requirements — do not overtighten, as this can damage the gauge socket. Verify the flange mounting surface is flat and secure before final tightening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 30 to 0 to 30 psi (compound)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.5% 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: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Rear Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWetted Parts 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: 2.5 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: 80252XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51538988663090,"sku":"80252XLL","price":746.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95f8bcdc83bc5f5350f7bcbd810e2402_9700afc2-b6c4-4bc7-89c3-7ece6f535a2c.jpg?v=1785831944","url":"https:\/\/voomisupply.com\/products\/ashcroft-80252xll-pressure-gauge-4-5-in-dial-30-0-30-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
