This pressure-rated fitting is used in potable water, hydronic heating, and general plumbing distribution systems where a copper-to-threaded joint is required. Cast from copper alloy per ASTM B584, it provides consistent wall thickness and reliable joint integrity under sustained system pressure. Licensed plumbers and pipefitters install this fitting as part of brazed or soldered copper assemblies where a transition to threaded pipe or a threaded valve, union, or equipment connection is needed.\u003c\/p\u003e\n\u003cp\u003eThis adapter suits residential and light commercial plumbing installations. It is used wherever a sweat copper main or branch line must connect to a female NPT-threaded component such as a ball valve, pressure gauge port, pump, or boiler fitting. The C x F configuration allows the field technician to solder the copper end to existing tubing while threading a male NPT nipple or fitting directly into the female port. Typical applications include domestic water supply, closed-loop hydronic systems, and radiant heating distribution manifolds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2 inch copper sweat (C) inlet by 1 inch female NPT (F) outlet transition\u003c\/li\u003e\n  \u003cli\u003eCast copper alloy construction per ASTM B584 for uniform density and pressure integrity\u003c\/li\u003e\n  \u003cli\u003ePressure fitting style rated for standard plumbing system operating pressures\u003c\/li\u003e\n  \u003cli\u003eFNPT thread standard for direct connection to male NPT pipe, valves, or equipment\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B584 and ISO standards\u003c\/li\u003e\n  \u003cli\u003eSingle-piece unit with no internal components to wear or fail\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pressure fitting for copper sweat-to-female NPT plumbing assemblies in residential and commercial water and hydronic systems.

Shut off and drain the system and verify zero pressure before cutting into the line or disassembling any existing joint. The sweat end is soldered using standard lead-free solder and flux per local plumbing code; the FNPT port accepts a male NPT fitting with thread sealant or PTFE tape applied to the male threads only. Follow IPC and local code requirements for pressure testing before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Adapter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1-1\/2 inches x 1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: C x F (Copper 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\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\u003eStandards\u003c\/strong\u003e: ASTM B584, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.43 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175305\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: B026050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51541693104434,"sku":"B026050","price":58.32,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad82fd8b051033daab23359654adfdff_c7d2a40b-e998-49ef-91f4-d31c3729b9c5.jpg?v=1785882316","url":"https:\/\/voomisupply.com\/products\/nibco-b026050-cast-copper-adapter-1-1-2x1-in-c-x-f","provider":"Voomi Supply","version":"1.0","type":"link"}
