This fitting measures 5-3\/4 inches and uses a C x F end connection, meaning one end accepts a sweat (copper) connection and the other end features female NPT threads. Cast from copper alloy per ASTM B584, the B029800 provides reliable performance in pressure service. It is installed by licensed plumbers and pipefitters working on copper water distribution systems where a transition from soldered copper to threaded pipe or a fixture connection is required.\u003c\/p\u003e\n\u003cp\u003eThis drop adapter is suited for installations where a copper supply line must connect to a female-threaded fitting, valve, or fixture. The sweat-by-FNPT configuration is common in residential water supply rough-in work, commercial restroom fixture connections, and light commercial plumbing where copper pressure piping meets threaded components. The 5-3\/4 inch fitting size accommodates larger-diameter pipe runs requiring a robust, code-compliant transition fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast copper construction per ASTM B584 for pressure service durability\u003c\/li\u003e\n  \u003cli\u003eC x F end connection: sweat inlet with female NPT threaded outlet\u003c\/li\u003e\n  \u003cli\u003e5-3\/4 inch fitting size for larger-diameter copper pipe systems\u003c\/li\u003e\n  \u003cli\u003ePressure fitting style rated for water distribution service\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B584 and ISO standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pressure fitting replacement for copper pipe systems using C x F (sweat by female NPT) connections in residential and commercial plumbing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber. Shut off the water supply and depressurize the line before soldering or making any threaded connections. The sweat end requires proper flux application, reaming, and a clean, dry pipe surface before soldering per accepted copper joining practices. Apply thread sealant or PTFE tape to the FNPT threads before assembling to the mating component. Work should comply with the International Plumbing Code and applicable local codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Drop Adapter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 5-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Pressure Fitting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: C x F (Sweat x Female NPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM B584, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: B029800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51541464711474,"sku":"B029800","price":86.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b25770616ccb12c9571ab8faf4dba9c.jpg?v=1785876896","url":"https:\/\/voomisupply.com\/products\/nibco-b029800-cast-copper-drop-adapter-5-3-4-in-c-x-f","provider":"Voomi Supply","version":"1.0","type":"link"}
