The 2-1\/2 inch dial provides a clear, readable display with a single scale ranging from 0 to 100 psi. Glycerine fill dampens pointer vibration and protects internal components from pressure spikes, making this gauge well-suited for hydraulic lines, compressed air systems, and process piping. The stainless steel case and stainless steel wetted parts resist corrosion in wet or chemically active environments. Accuracy is rated at plus or minus 2-1\/2 percent of full scale. The lower-mount 1\/4 inch NPT connection allows direct inline or panel installation without additional adapters in most standard configurations.\u003c\/p\u003e\n\u003cp\u003eThis gauge fits residential and light commercial applications where durable, corrosion-resistant instrumentation is required. Typical installations include HVAC hydronic systems, boiler supply and return lines, water treatment equipment, compressed air distribution, and general process piping. The glycerine fill makes it appropriate for pump discharge monitoring and other high-vibration service points. Licensed plumbers, pipefitters, HVAC technicians, and industrial maintenance technicians are the primary installers of this type of gauge.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGlycerine-filled case dampens vibration and protects against pressure spikes\u003c\/li\u003e\n  \u003cli\u003eStainless steel wetted parts resist corrosion in aggressive media\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel case for durable, weather-resistant housing\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch analog dial for clear on-site pressure readings\u003c\/li\u003e\n  \u003cli\u003ePlus or minus 2-1\/2 percent of full scale accuracy\u003c\/li\u003e\n  \u003cli\u003eLower-mount 1\/4 inch NPT connection for standard inline or manifold installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation gauge for systems requiring a 1\/4 inch NPT lower-mount pressure gauge with a 0 to 100 psi range and 2-1\/2 inch dial diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable local codes and ASME B40.100 pressure gauge standards. Isolate and depressurize the system fully before removing an existing gauge or installing this unit. Use PTFE thread tape or appropriate pipe sealant on the NPT threads — do not overtighten, as this can crack the gauge socket. Avoid installing in service where system pressure may exceed the rated maximum of 100 psi.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 100 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2-1\/2 inches (63 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScale Type\u003c\/strong\u003e: Single, analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: Plus or minus 2-1\/2 percent of full scale\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: Lower mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: Yes, glycerine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWetted Parts Material\u003c\/strong\u003e: Stainless steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: 304 stainless steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel Number\u003c\/strong\u003e: 233.54\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: WIKA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9831881\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIKA","offers":[{"title":"Default Title","offer_id":51708781822258,"sku":"9831881","price":228.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2d884e730a5507cf09d6b93edbaa857.jpg?v=1788448317","url":"https:\/\/voomisupply.com\/products\/wika-9831881-pressure-gauge-0-100-psi-2-1-2-in-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
