It features a 2-inch stainless steel case with brass wetted parts and a glycerine or water fill that dampens needle vibration and protects the internal Bourdon tube in pulsating or high-vibration systems. The gauge reads a dual-scale range of 30 psi vacuum to 30 psi positive pressure, with an accuracy rating of plus or minus 3-2-3 percent of scale. The 1\/4-inch NPT center back mount connection allows direct panel or pipe installation without external fittings in most standard configurations. Licensed plumbers, HVAC technicians, and pipefitters are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis gauge is suited for residential and light commercial systems where monitoring both vacuum and positive pressure is required — including refrigeration service, boiler systems, compressed air lines, water supply lines, and pump suction and discharge monitoring. The center back mount configuration fits standard pipe nipple and panel cutout installations. The glycerine fill makes it appropriate for environments with moderate vibration or pressure pulsation where a dry gauge would flutter and wear prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-scale range: 30 inches Hg vacuum to 30 psi positive pressure on a single dial\u003c\/li\u003e\n  \u003cli\u003eGlycerine or water liquid fill dampens needle vibration and extends service life in pulsating systems\u003c\/li\u003e\n  \u003cli\u003eStainless steel case resists corrosion in wet or outdoor service environments\u003c\/li\u003e\n  \u003cli\u003eBrass wetted parts and bronze Bourdon tube compatible with water, air, and non-corrosive gases\u003c\/li\u003e\n  \u003cli\u003ePlus or minus 3-2-3 percent of scale accuracy meets standard industrial gauge requirements\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPT center back mount for direct panel or pipe installation\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 residential and light commercial systems requiring a 2-inch dial, 1\/4-inch NPT center back mount pressure gauge with a 30 psi range and liquid fill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or pipefitter. Shut off and depressurize the system completely before removing an existing gauge or installing a new one. Apply thread sealant or PTFE tape to the NPT threads per standard practice — do not overtighten, as brass fittings are susceptible to thread damage. Verify the pressure range of the system does not exceed the 30 psi maximum rating of this gauge before placing it 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\u003eMaximum Pressure\u003c\/strong\u003e: 30 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: +\/- 3-2-3% of scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2 inches (38.13 mm)\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\u003eLiquid Filled\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Fill Type\u003c\/strong\u003e: Glycerine or Water\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBourdon Tube Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWetted Parts Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.5 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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41112412\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: 115AB20V30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715567223090,"sku":"115AB20V30","price":27.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34b855451dae67d332118bda440df9a2.jpg?v=1788515722","url":"https:\/\/voomisupply.com\/products\/value-collection-115ab20v30-pressure-gauge-30-psi-2-in-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
