It features a 2-1\/2 inch analog dial with a 0 to 200 psi single scale, providing clear readings across a wide pressure range. The brass case and copper alloy wetted parts offer solid corrosion resistance in typical plumbing, HVAC, and light industrial environments. Accuracy is rated at 1.5 percent of full scale. The acrylic lens protects the dial face while maintaining readability. This gauge is installed by licensed plumbers, pipefitters, HVAC technicians, and maintenance engineers wherever reliable pressure indication is required.\u003c\/p\u003e\u003cp\u003eThe WIKA 9318194 is suited for residential and commercial mechanical systems where a back-mount configuration is needed to mount flush against a panel or pipe assembly. It is commonly used on boilers, chillers, compressors, pumps, and hydraulic or pneumatic circuits operating within the 0 to 200 psi range. The glycerine fill dampens pointer vibration and reduces wear on the internal movement, making it appropriate for applications with pulsating or fluctuating pressure. The 1\/4 inch NPT back-mount connection is a standard fitting size found throughout trade plumbing and HVAC piping systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0 to 200 psi single-scale analog dial for broad pressure range coverage\u003c\/li\u003e\n\u003cli\u003eGlycerine-filled case dampens vibration and extends gauge service life\u003c\/li\u003e\n\u003cli\u003e1.5 percent of full scale accuracy for reliable process monitoring\u003c\/li\u003e\n\u003cli\u003e2-1\/2 inch dial diameter for easy reading at typical service distances\u003c\/li\u003e\n\u003cli\u003eBrass case with copper alloy wetted parts for corrosion resistance in standard media\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPT back-mount connection for flush panel or pipe installations\u003c\/li\u003e\n\u003cli\u003eAcrylic lens protects dial face from dust and minor impact\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation pressure gauge for industrial, commercial, and residential mechanical systems using standard 1\/4 inch NPT back-mount connections with operating pressures up to 200 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Always depressurize and isolate the system before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads per applicable IPC and IFGC guidelines, and avoid overtightening, which can crack the brass case or damage the socket. Do not use this gauge on oxygen or acetylene service without confirming compatibility with the service medium.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 200 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1.5 percent of full scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog, single scale\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\u003eMount Type\u003c\/strong\u003e: Back mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: Yes, glycerine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWetted Parts Material\u003c\/strong\u003e: Copper alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Acrylic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.66 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: WIKA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9318194\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIKA","offers":[{"title":"Default Title","offer_id":51691317788978,"sku":"9318194","price":182.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a36b280dcae4834b889d2335bac5212a.jpg?v=1788283188","url":"https:\/\/voomisupply.com\/products\/wika-9318194-pressure-gauge-0-200-psi-2-1-2-in-back-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
