Rated at 175 psi and Class 250, this cast iron flange provides a robust mechanical connection point in industrial and commercial piping systems. The flange features 8 bolt holes spaced across 5-3\/4-inch bolt hole centers, with each bolt hole measuring 7\/8 inch. It is installed by licensed plumbers and pipefitters working on pressure piping systems where a reliable, code-compliant threaded flange connection is required.\u003c\/p\u003e\u003cp\u003eThis threaded pipe flange is suited for commercial and industrial piping applications where cast iron flanged connections are specified. It is commonly installed in mechanical rooms, process piping, water distribution, and steam or hydronic systems that require flanged joints at equipment connections, valve isolation points, or pipe terminations. The Class 250 pressure rating makes it appropriate for moderate-to-high pressure service conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass 250 pressure rating at 175 psi working pressure\u003c\/li\u003e\n\u003cli\u003e4-inch pipe size with 10-inch outer diameter\u003c\/li\u003e\n\u003cli\u003e8-bolt pattern with 7\/8-inch bolt holes on 5-3\/4-inch bolt circle\u003c\/li\u003e\n\u003cli\u003e1-3\/4-inch hub length for threaded pipe engagement\u003c\/li\u003e\n\u003cli\u003eCast iron construction for durability in industrial piping service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation threaded flange for 4-inch cast iron or compatible piping systems rated for Class 250 service.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or ASME B16.1 flanged fitting standards. The system must be fully depressurized and drained before removing or installing any flanged connection. Thread engagement and flange face alignment are critical to achieving a leak-free joint at rated pressure. Use appropriate gasket material and fastener torque patterns per the applicable piping specification.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter (OD)\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Hole Centers\u003c\/strong\u003e: 5-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Hole Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Bolt Holes\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 175 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass\u003c\/strong\u003e: 250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 20.15 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: ANVIL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0308501006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51542973448498,"sku":"0308501006","price":422.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a14fb3209e1a65d2e54d901aef431e9e.jpg?v=1785912767","url":"https:\/\/voomisupply.com\/products\/anvil-0308501006-threaded-pipe-flange-4-in-class-250","provider":"Voomi Supply","version":"1.0","type":"link"}
