It provides a 45-degree branch takeoff from a main run, allowing controlled directional changes or branch connections in supply and drain-adjacent pressure lines. The fitting uses a solder-cup end connection on all three ports (C x C x C), making it compatible with standard copper sweat joining methods. At 1.14 pounds, it is a solid, full-cast construction rather than a wrought fitting, which is suited for higher-stress connection points. Licensed plumbers and pipefitters are the primary installers for this type of pressure fitting.\u003c\/p\u003e\n\u003cp\u003eThis fitting is intended for residential and light commercial copper pressure piping applications where a 45-degree branch configuration is required. The 1-1\/2-inch size is common in domestic water distribution, recirculation lines, and hydronic supply systems. The C x C x C end connection style requires all three ports to be soldered, making this a fixed, permanent joint fitting appropriate for in-wall, mechanical room, or exposed copper rough-in work. It is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast copper construction meets ASTM B584 and ISO standards for pressure fittings\u003c\/li\u003e\n  \u003cli\u003e45-degree wye configuration allows branch takeoffs without sharp directional changes\u003c\/li\u003e\n  \u003cli\u003eThree solder-cup (C x C x C) ports for standard sweat-joint installation\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-inch fitting size suits common residential and commercial branch line sizing\u003c\/li\u003e\n  \u003cli\u003ePressure fitting style rated for use in pressurized copper piping systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pressure fitting for use with standard 1-1\/2-inch copper tubing in sweat-joint pressure piping systems conforming to ASTM B584 and ISO fitting standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and depressurize the water supply and allow all pipes to cool completely before cutting or fitting. Clean and flux all mating surfaces before applying heat; use appropriate lead-free solder for potable water systems. Do not apply heat directly to the fitting body for extended periods, as overheating cast copper fittings can compromise joint integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: 45 Degree Wye\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1-1\/2 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 C x C\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: 1.14 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: B345750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51541819031858,"sku":"B345750","price":191.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da809cd77056261216f0553aa8d2e4d4.jpg?v=1785885801","url":"https:\/\/voomisupply.com\/products\/nibco-b345750-cast-copper-45-wye-1-1-2-in-cxcxc","provider":"Voomi Supply","version":"1.0","type":"link"}
