It features a 2-inch diameter dial with a 0 to 30 psi range and a 1\/4-inch NPT lower-mount connection. The case is constructed from ABS (Acrylonitrile Butadiene Styrene) for durability in typical service environments, while the wetted parts are brass for compatibility with a wide range of fluid media. The gauge operates without liquid fill and reads through a plastic lens. It is installed by HVAC technicians, plumbers, and general service technicians wherever low-range pressure monitoring is required.\u003c\/p\u003e\u003cp\u003eThis gauge is suited for residential and light commercial installations where a compact, no-fill pressure gauge is needed. Common applications include monitoring supply or return pressures on hydronic heating systems, water supply lines, compressed air circuits, and similar low-pressure systems. The lower-mount NPT connection makes panel mounting or direct pipe-tee installation straightforward in tight spaces where a bottom-entry connection is practical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-inch dial diameter for easy reading in compact installations\u003c\/li\u003e\n\u003cli\u003e0 to 30 psi pressure range suitable for low-pressure water and air circuits\u003c\/li\u003e\n\u003cli\u003e1\/4-inch NPT lower-mount connection for direct pipe or panel installation\u003c\/li\u003e\n\u003cli\u003eBrass wetted parts for broad fluid compatibility\u003c\/li\u003e\n\u003cli\u003eABS case construction for lightweight durability\u003c\/li\u003e\n\u003cli\u003eNo-fill design reduces maintenance and eliminates fluid-leak concerns\u003c\/li\u003e\n\u003cli\u003e3-2-3 percent of scale accuracy across the full dial range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service addition for commercial pressure gauge applications requiring a 2-inch dial, 1\/4-inch NPT lower-mount connection, and a 0 to 30 psi range.

Shut off and depressurize the system completely before removing or installing any pressure gauge. Use appropriate thread sealant on the NPT connection and tighten by hand first before using a wrench to avoid overtightening the brass fitting. Do not exceed the rated pressure range of the gauge.\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\u003eDial Diameter\u003c\/strong\u003e: 2 inches (50 mm)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 3-2-3 percent of 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\u003eCase Material\u003c\/strong\u003e: ABS (Acrylonitrile Butadiene Styrene)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWetted Parts Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquid Fill\u003c\/strong\u003e: No-Fill\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 4252901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIKA","offers":[{"title":"Default Title","offer_id":51701722906930,"sku":"4252901","price":64.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2c288d5ed29b7420c6d7433b57acd25.jpg?v=1788404350","url":"https:\/\/voomisupply.com\/products\/wika-4252901-pressure-gauge-0-30-psi-2-in-dial-npt-lower","provider":"Voomi Supply","version":"1.0","type":"link"}
