Built to a 150 psi pressure rating, this flange accommodates 4-inch pipe with a 9-inch outer diameter and features female threaded end connections for straightforward field installation. Bolt hole centers are spaced 7.5 inches across, conforming to standard flange bolt patterns. Licensed plumbers and pipefitters install this type of fitting in a wide range of commercial and industrial piping applications where copper material compatibility is required.\u003c\/p\u003e\n\u003cp\u003eThis flange is suited for commercial and industrial piping systems where threaded copper fittings are specified. The companion flange style allows it to be paired with a mating flange to form a bolted, gasketed joint — a common configuration in mechanical rooms, boiler rooms, and process piping installations. Its 150 psi pressure rating makes it appropriate for low-to-medium pressure liquid service applications. The threaded female connection end accommodates standard NPT-threaded pipe for assembly without welding or soldering.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast copper construction for corrosion resistance in plumbing and piping service\u003c\/li\u003e\n  \u003cli\u003e150 psi pressure rating for low-to-medium pressure liquid systems\u003c\/li\u003e\n  \u003cli\u003e4-inch pipe size with 9-inch outer diameter\u003c\/li\u003e\n  \u003cli\u003eFemale threaded (F) end connection for NPT pipe assembly\u003c\/li\u003e\n  \u003cli\u003e7.5-inch bolt hole circle spacing for standard flange bolt patterns\u003c\/li\u003e\n  \u003cli\u003eCompanion flange style designed to mate with a corresponding flange fitting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation companion pipe flange for 4-inch threaded copper piping systems rated to 150 psi service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing code requirements. Shut off and depressurize the piping system completely before disassembling any flanged joint. Use an appropriate flange gasket and torque fasteners evenly in a cross pattern to ensure a uniform seal — consult applicable flange standards for fastener specifications. Do not exceed the 150 psi rated working pressure of this fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Threaded Companion\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Circle\u003c\/strong\u003e: 7.5 inches across centers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Female Threaded (F)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.2 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: NIBCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B515456\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51540300431666,"sku":"B515456","price":1085.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/871360b04f5273513fcd29e4a787d764_7d7970ce-1ecd-4e6d-b629-ee2030b37234.jpg?v=1785851506","url":"https:\/\/voomisupply.com\/products\/nibco-b515456-cast-copper-threaded-companion-flange-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
