The gauge features a 2.5-inch dial with a 0 to 30 psi range, a lower-mount 1\/4-inch NPT connection, and a glycerine-filled case that dampens needle vibration for steady readings in high-cycle or pulsating-flow systems. The stainless steel case resists corrosion in wet or outdoor service environments. Accuracy is rated at plus or minus 3-2-3 percent of scale. A licensed plumber, HVAC technician, or pipefitter typically handles installation of gauges of this type.\u003c\/p\u003e\u003cp\u003eThis gauge is suited for residential and light commercial systems where a compact 2.5-inch face and lower-mount NPT fitting are required. Common applications include water pressure monitoring on supply lines, boiler systems, compressed-air headers, and hydronic loops operating at or below 30 psi. The bronze Bourdon tube and brass wetted parts are compatible with water, glycerine solutions, and other non-corrosive media. The glycerine fill helps maintain readability in environments with vibration or pressure fluctuation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0 to 30 psi analog pressure range with plus or minus 3-2-3 percent of scale accuracy\u003c\/li\u003e\n\u003cli\u003e2.5-inch dial diameter for clear, at-a-glance readings\u003c\/li\u003e\n\u003cli\u003eGlycerine liquid fill dampens vibration and pulsation for stable needle position\u003c\/li\u003e\n\u003cli\u003eLower-mount 1\/4-inch NPT connection for direct inline or manifold installation\u003c\/li\u003e\n\u003cli\u003eStainless steel case provides corrosion resistance in wet service environments\u003c\/li\u003e\n\u003cli\u003eBrass wetted parts and bronze Bourdon tube suited for water and non-corrosive media\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or new-installation pressure gauge for plumbing, HVAC, and light industrial systems using 1\/4-inch NPT lower-mount fittings with a maximum operating pressure of 30 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician. Shut off system pressure and depressurize the line fully before threading the gauge into the fitting. Apply thread sealant or PTFE tape to the NPT threads per IPC and local code requirements. Do not over-tighten the gauge body; use the hex flats on the connection fitting to avoid stressing the case or Bourdon tube.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 30 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: plus or minus 3-2-3 percent of scale\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\u003eMount Type\u003c\/strong\u003e: Lower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: 1\/4 inch 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\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 115AL25030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51705318080818,"sku":"115AL25030","price":27.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92a96415d066d42b412f0786d253b3d6.jpg?v=1788428204","url":"https:\/\/voomisupply.com\/products\/value-collection-115al25030-pressure-gauge-30-psi-lower-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
