Featuring a 4.5 inch dial face and a 0 to 200 psi measurement range, this gauge delivers 0.5 percent of scale accuracy for reliable readings in the field. The thermoplastic case resists corrosion and reduces weight, making it a practical choice for permanent installations and portable test rigs alike. The no-fill design eliminates the risk of fluid contamination in dry-service environments. Licensed technicians and service professionals install this gauge where a clear, large-format readout is required at rear-entry panel or manifold positions.\u003c\/p\u003e\n\u003cp\u003eThis gauge is suited for residential and light commercial HVAC systems, hydronic heating loops, water supply lines, compressed air systems, and general plumbing test setups. The rear flange mount allows secure panel or bulkhead installation, keeping the dial face flush and visible. The 1\/4 inch threaded connection is a common size across manifolds, valves, and test ports, minimizing the need for additional adapters in most service scenarios.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5 inch analog dial face for easy reading at a distance\u003c\/li\u003e\n  \u003cli\u003e0 to 200 psi range covers a wide range of residential and light commercial pressure applications\u003c\/li\u003e\n  \u003cli\u003e0.5 percent of scale accuracy for reliable field measurements\u003c\/li\u003e\n  \u003cli\u003eThermoplastic case is lightweight and corrosion-resistant\u003c\/li\u003e\n  \u003cli\u003eNo-fill design eliminates liquid contamination concerns in dry-service use\u003c\/li\u003e\n  \u003cli\u003eRear flange mount enables secure panel or bulkhead installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install gauge for systems with a standard 1\/4 inch NPT rear-entry port and rear flange panel mounting, typical in HVAC, plumbing, and compressed air service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this pressure gauge should be performed by a licensed HVAC technician, plumber, or qualified service professional. Shut off and relieve all system pressure before removing or installing any pressure gauge. Use appropriate thread sealant on the 1\/4 inch connection per applicable codes, such as IPC or IFGC, and avoid over-tightening the fitting into the port. Confirm the system operating pressure does not exceed the 200 psi full-scale rating of this gauge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 200 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.5 percent of scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Rear Flange\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: Thermoplastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ASHCROFT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 96251\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51542866493746,"sku":"96251","price":473.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/760f8efc512ec2bc85a40aae2d63044d_26e09b1a-f49d-4314-9e4e-95646e49695d.jpg?v=1785909357","url":"https:\/\/voomisupply.com\/products\/ashcroft-96251-pressure-gauge-4-5-in-dial-0-200-psi-rear-flange","provider":"Voomi Supply","version":"1.0","type":"link"}
