This adapter features a 2-1\/2 inch cup connection on one end and a 2-1\/2 inch flange on the other, making it suitable for connecting copper tube to flanged equipment, valves, pumps, and piping systems. It is manufactured from C12200 wrot copper, a high-purity phosphorus-deoxidized copper alloy known for its excellent solderability, corrosion resistance, and long service life in potable water applications. The cup end accepts standard 2-1\/2 inch copper tubing and is joined using heat and solder for a permanent, leak-tight sweat connection. The flanged end allows for bolted connections with easy disassembly for future inspection, cleaning, or system modification. This type of fitting is widely used by licensed plumbers, mechanical contractors, and commercial plumbing technicians on water supply systems, hydronic heating systems, and industrial process piping. The fitting meets low-lead content standards, making it compliant for use in drinking water systems under NSF\/ANSI\/CAN-61. It also conforms to ASME\/ANSI B16.22 and MSS SP-104 standards, ensuring dimensional accuracy and pressure performance. The flange outside diameter measures 7 inches with a thickness of 5\/8 inches and includes 4 bolt holes, each with a 3\/4 inch diameter. The fitting handles a temperature range of -20 degrees Fahrenheit to 275 degrees Fahrenheit, covering most commercial and residential hydronic and domestic water applications. Manufactured in the USA, this copper flange adapter is a dependable choice for trade professionals who need a code-compliant, pressure-rated copper sweat flange fitting.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCup x flange configuration allows direct sweat connection of 2-1\/2 inch copper tubing to flanged equipment or piping\u003c\/li\u003e\n\u003cli\u003eC12200 wrot copper construction provides superior corrosion resistance and durability in potable water systems\u003c\/li\u003e\n\u003cli\u003eCompliant with NSF\/ANSI\/CAN-61, ASME\/ANSI B16.22, and MSS SP-104 for use in drinking water and pressure-rated applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe NIBCO 9405555 wrot copper sweat flange adapter offers a code-compliant, low-lead solution for connecting 2-1\/2 inch copper tube to flanged systems, delivering reliable performance across a wide temperature range in potable water and commercial plumbing applications.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9405555\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Material\u003c\/strong\u003e: C12200 Wrot Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -20 F to 275 F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Tube Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide A Connection\u003c\/strong\u003e: Cup\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide A Compatible Tube Outer Diameter\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide A Copper Tube Size\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide B Connection\u003c\/strong\u003e: Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide B Pipe Size\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Thickness\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Outside Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Hole Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Bolt Holes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Media Type\u003c\/strong\u003e: Potable Water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME\/ANSI B16.22; MSS SP-104; NSF\/ANSI\/CAN-61\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51120859742514,"sku":"9405555","price":123.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304883056.jpg?v=1777741680","url":"https:\/\/voomisupply.com\/products\/nibco-9405555-sweat-fitting-adapter-2-1-2-in-cup-x-2-1-2-in-flange-wrot-copper","provider":"Voomi Supply","version":"1.0","type":"link"}
