It delivers dual-scale readings covering 0 to 30 psi and 0 to 760 mmHg, making it suitable for low-pressure monitoring across a wide range of trade applications. The stainless steel case provides corrosion resistance in demanding service environments. Accuracy is rated at 1.5 percent of scale, which meets standard industrial and mechanical service requirements. HVAC technicians, plumbers, and mechanical contractors install this gauge for pressure monitoring on refrigeration systems, water lines, gas lines, and general mechanical service panels.\u003c\/p\u003e\u003cp\u003eThis gauge is suited for residential and light commercial installations where a durable, easy-to-read dial instrument is required. The lower-mount configuration positions the inlet at the 6 o'clock position on the gauge body, which is the standard orientation for panel and pipe-mounted applications. The 4-inch dial provides clear readability at typical working distances on a mechanical room or equipment panel. The dual pressure scale is useful in applications that require both psi and mmHg reference, including vacuum and low-pressure refrigeration or fluid system diagnostics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch analog dial for easy readability in panel and field installations\u003c\/li\u003e\n\u003cli\u003eDual pressure range: 0 to 30 psi and 0 to 760 mmHg\u003c\/li\u003e\n\u003cli\u003e1.5 percent of scale accuracy for reliable low-pressure measurement\u003c\/li\u003e\n\u003cli\u003eLower-mount 1\/4-inch thread connection fits standard pipe and manifold fittings\u003c\/li\u003e\n\u003cli\u003eStainless steel case resists corrosion in wet or chemically active environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation analog pressure gauge for residential and light commercial mechanical systems requiring a 4-inch lower-mount dial instrument with 1\/4-inch thread connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or mechanical contractor. Shut off and depressurize the system before removing an existing gauge or connecting this gauge to any live line. Use appropriate thread sealant or PTFE tape on the 1\/4-inch male connection per the system manufacturer and applicable plumbing or mechanical code requirements. Do not overtighten the gauge connection, as stainless bourdon tube gauges can be damaged by excessive torque at the socket joint.\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 \/ 0 to 760 mmHg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1.5 percent of scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Lower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.32 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: 9747740\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIKA","offers":[{"title":"Default Title","offer_id":51692841402674,"sku":"9747740","price":419.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf1b5c2082e8a1fa76f52d30f730c8af.jpg?v=1788303869","url":"https:\/\/voomisupply.com\/products\/wika-9747740-pressure-gauge-4-inch-dial-lower-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
