It features a Fitting (FTG) male solder end on one side and a Male Pipe Tapered Thread (MPT\/NPT) end on the other, both sized at 1-1\/2 inches. This configuration allows plumbers and pipefitters to transition seamlessly between a copper solder-joint connection and a threaded pipe connection in a single fitting. The FTG end accepts a standard copper pipe or fitting socket, while the MPT end threads directly into a female-threaded valve, fitting, or equipment port. This type of adapter is commonly used when connecting copper water supply lines to threaded valves, manifolds, water heaters, pumps, or other plumbing components that require a male NPT thread entry point. Wrot copper construction means the fitting is formed by working the copper material, resulting in a dense, strong grain structure with excellent corrosion resistance and long service life. Wrot copper fittings are the preferred choice for residential and commercial plumbing installations where reliability and leak-free performance are critical. The W01479 meets NSF 61G certification, confirming it is safe for contact with potable drinking water. It also conforms to multiple ASME standards covering solder-joint and threaded copper fittings, ensuring dimensional accuracy and compatibility with standard copper pipe systems. At 0.49 pounds, the fitting is sturdy yet easy to handle during installation. Mueller Streamline has been a trusted name in copper solder-joint fittings for over 80 years, and this adapter reflects that legacy of precision manufacturing and consistent quality. It is a reliable solution for plumbing professionals working on water supply rough-in, retrofit, or repair projects.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFTG (male solder) x MPT (male NPT thread) adapter — 1-1\/2 inches on both ends\u003c\/li\u003e\n\u003cli\u003eWrot copper construction for superior strength, corrosion resistance, and long service life\u003c\/li\u003e\n\u003cli\u003eNSF 61G certified for potable water contact and compliant with multiple ASME standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Mueller Streamline W01479 wrot copper adapter fitting provides a reliable FTG-to-MPT transition for 1-1\/2 inch potable water supply systems, meeting NSF 61G and ASME dimensional standards for professional plumbing installations.\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: MUELLER STREAMLINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W01479\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Wrot Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.49 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: FTG - Fitting (Male Solder)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecond End Type\u003c\/strong\u003e: MPT - Male Pipe Tapered Thread (NPT)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecond End Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NSF 61G, ASME B16.15, ASME B16.18, ASME B16.22, ASME B16.24, ASME B16.50, ASME B1.20.1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51120831004978,"sku":"W01479","price":144.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304882183.jpg?v=1777740766","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-w01479-wrot-copper-adapter-fitting-ftg-x-mpt-1-1-2-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
