It features a 2.5-inch dial face with a 0 to 160 psi range and a 1\/8-inch center back mount connection. The front flange mount design allows for panel or bulkhead installation without additional hardware. Accuracy is rated at plus or minus 3-2-3 percent of scale, meaning 3 percent at the lower and upper ranges and 2 percent through the mid-range. Plumbers, HVAC technicians, and mechanical contractors install this gauge to verify operating pressure on closed systems, test ports, and service panels.\u003c\/p\u003e\u003cp\u003eThis gauge suits residential and light commercial systems where a compact dial size and standard 1\/8-inch NPT back connection are required. The front flange mounting style is common on panel-mounted gauge boards and manifold assemblies. It is appropriate for use on water supply lines, refrigerant manifolds, compressed air circuits, and similar low-to-medium pressure fluid systems operating within the 0 to 160 psi range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.5-inch analog dial face for easy field reading\u003c\/li\u003e\n\u003cli\u003e0 to 160 psi pressure range suits common HVAC and plumbing service pressures\u003c\/li\u003e\n\u003cli\u003ePlus or minus 3-2-3 percent of scale accuracy across the full range\u003c\/li\u003e\n\u003cli\u003e1\/8-inch center back mount connection for standard NPT fittings\u003c\/li\u003e\n\u003cli\u003eFront flange design supports panel or bulkhead mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service gauge for residential and light commercial systems requiring a 2.5-inch dial, 1\/8-inch center back mount pressure gauge rated to 160 psi.

Depressurize and isolate the system before removing any existing gauge or fitting. Use appropriate thread sealant on the 1\/8-inch NPT connection per local plumbing or mechanical code requirements. Do not over-tighten the gauge body; use a wrench on the hex fitting only, not on the dial case.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 160 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: plus or minus 3-2-3 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: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Front Flange, Center Back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Number\u003c\/strong\u003e: P845FFK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.45 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: AMETEK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 164454\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AMETEK","offers":[{"title":"Default Title","offer_id":51540581515570,"sku":"164454","price":104.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bd712a96d3710ade11bbf3dc012e2d7.jpg?v=1785859027","url":"https:\/\/voomisupply.com\/products\/ametek-164454-pressure-gauge-2-5-in-0-160-psi-center-back-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
