The gauge features a 2.5-inch dial and reads from -30 inches Hg to 0 to 30 psi, making it suited for both low-pressure and compound measurement tasks. A glycerine and water fill dampens needle movement under pulsating or vibrating conditions. The stainless steel case provides corrosion resistance, and brass wetted parts offer reliable compatibility with common media. Licensed plumbers, HVAC technicians, and industrial maintenance professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis gauge is configured for lower mount installation using a 1\/4-inch NPT threaded connection. It is appropriate for residential and light commercial plumbing systems, hydronic heating circuits, refrigeration support lines, and general fluid pressure monitoring where a compact dial size and liquid fill are specified. The compound scale (-30 Hg to 30 psi) supports both pressure and vacuum readings from a single instrument, reducing the need for separate gauges in mixed-service panels or manifolds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.5-inch analog dial for clear on-site readability\u003c\/li\u003e\n  \u003cli\u003eCompound range: -30 inches Hg vacuum to 30 psi positive pressure\u003c\/li\u003e\n  \u003cli\u003eGlycerine and water liquid fill reduces needle flutter in vibrating systems\u003c\/li\u003e\n  \u003cli\u003eStainless steel case for corrosion-resistant durability\u003c\/li\u003e\n  \u003cli\u003eBrass wetted parts compatible with common plumbing and HVAC media\u003c\/li\u003e\n  \u003cli\u003eLower mount, 1\/4-inch NPT connection for standard panel and inline installations\u003c\/li\u003e\n  \u003cli\u003ePlus or minus 3-2-3 percent of scale accuracy across the full range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install gauge for residential and light commercial plumbing, hydronic, and HVAC systems requiring a lower-mount, 1\/4-inch NPT, liquid-filled compound pressure gauge 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 plumber or qualified HVAC technician in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Shut off system pressure and depressurize the line before removing any existing gauge or fitting. Apply thread sealant or PTFE tape to the NPT threads before installation — do not overtighten, as brass fittings are susceptible to damage. Verify the pressure range of the gauge is appropriate for the system before placing the line back in 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 30 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\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\u003eMount Type\u003c\/strong\u003e: Lower\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: 1\/4 inches NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Fill Type\u003c\/strong\u003e: Glycerine and Water\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: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBourdon Tube Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 115AL25V30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701971386674,"sku":"115AL25V30","price":28.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83984bfab2bb8572dbbf70896b9b95c4.jpg?v=1788407594","url":"https:\/\/voomisupply.com\/products\/value-collection-115al25v30-pressure-gauge-30-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
