It features a C x F (sweat x female) end connection, allowing a soldered joint on one side and a threaded female connection on the other. Sized at 1\/4 inch, this union is suited for low-volume or instrument line applications where a separable, rebuildable joint is needed without cutting into the line. Licensed plumbers and pipefitters install this fitting in residential and light commercial systems where periodic disconnection of a copper run is required.\u003c\/p\u003e\u003cp\u003eThis union is appropriate for residential plumbing, hydronic heating distribution lines, and other copper pressure systems where a demountable joint is specified. The C x F configuration makes it a practical choice when transitioning between a soldered copper run and a threaded component such as a valve, gauge, or equipment connection. It is sold individually and is intended for professional installation in code-compliant copper pressure piping assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCast copper construction for reliable performance in copper pressure systems\u003c\/li\u003e\n\u003cli\u003eC x F end connection supports sweat-to-female-thread transitions\u003c\/li\u003e\n\u003cli\u003ePressure fitting style rated for use in pressurized copper lines\u003c\/li\u003e\n\u003cli\u003e1\/4 inch fitting size suited for instrument, control, or small-branch applications\u003c\/li\u003e\n\u003cli\u003eRebuildable union design allows line separation without cutting pipe\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit union for 1\/4 inch copper pressure piping systems using sweat and female threaded end connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the system and allow all lines to cool completely before beginning work. The sweat end requires proper flux application and a clean, deburred pipe surface prior to soldering. Do not overtighten the union nut on the female threaded side; use an appropriate thread sealant compatible with copper fittings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/4 inches\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 Thread)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Pressure Fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: NIBCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B258500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51540716519730,"sku":"B258500","price":69.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ff8d4675829a9cf276927fe22fa1c97.jpg?v=1785862785","url":"https:\/\/voomisupply.com\/products\/nibco-b258500-cast-copper-union-1-4-in-c-x-f","provider":"Voomi Supply","version":"1.0","type":"link"}
