It features a 2-inch dial with a 0 to 30 psi range, making it well suited for low-pressure fluid and gas systems. The gauge uses a 1\/4-inch NPT center back mount connection, allowing direct inline or panel installation. The ABS case and plastic lens keep weight low at 0.2 pounds, while brass wetted parts provide compatibility with common water, oil, and gas media. Accuracy is rated at 3-2-3 percent of scale across the full range.\u003c\/p\u003e\u003cp\u003eThis gauge fits residential and light commercial service work where a compact, economical pressure indicator is needed. Typical applications include water supply lines, air compressor outlets, pump discharge monitoring, and HVAC hydronic circuits. The center back mount orientation suits panel-mounted or direct pipe installations where the face must be readable from the front. The no-fill, dry-bourdon design keeps maintenance minimal in clean-media environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0 to 30 psi range with single analog scale for straightforward low-pressure monitoring\u003c\/li\u003e\n\u003cli\u003e2-inch dial diameter for compact installations with clear readability\u003c\/li\u003e\n\u003cli\u003e1\/4-inch NPT center back mount connection for direct pipe or panel use\u003c\/li\u003e\n\u003cli\u003eBrass wetted parts compatible with water, light oils, and dry gases\u003c\/li\u003e\n\u003cli\u003eABS case with plastic lens — lightweight at 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e3-2-3 percent of scale accuracy across the full pressure range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service addition for residential and light commercial systems requiring a 2-inch NPT back-mount pressure gauge rated to 30 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or qualified service technician. Shut off and depressurize the system fully before removing or installing any pressure gauge. Apply thread sealant tape appropriate to the media — PTFE tape is standard for water and air — to the 1\/4-inch NPT male threads before threading into the port. Do not over-tighten; use a wrench on the hex fitting only, not on the case body.\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\u003eDial Type\u003c\/strong\u003e: Analog, single scale\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\u003eThread Size and Type\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Center back mount\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: ABS (Acrylonitrile Butadiene Styrene)\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 (dry)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 4253272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIKA","offers":[{"title":"Default Title","offer_id":51691241570610,"sku":"4253272","price":56.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e30fc3fe3ea3b21eba77439c6c8ce560.jpg?v=1788282014","url":"https:\/\/voomisupply.com\/products\/wika-4253272-pressure-gauge-0-30-psi-2-in-dial-npt-back-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
