It features a 1-inch male solder end (FTG) on one side and a 1\/2-inch female solder cup end (C) on the other, making it the right choice whenever a plumber needs to transition from a larger pipe diameter down to a smaller one in a copper piping system. The FTG, or fitting, end is sized to insert directly into a standard copper cup fitting, while the C, or cup, end receives standard copper tubing. This combination gives installers flexibility when building or modifying water distribution lines. Wrot copper is a wrought, or worked, copper material known for its tight grain structure, excellent strength, and reliable leak-free performance when properly soldered. The w01339 is manufactured to applicable ASME standards including B16.18 and B16.22, which govern cast copper alloy and wrought copper solder-joint pressure fittings respectively. It also meets NSF 61G requirements, confirming its suitability for use in potable drinking water systems. Mueller Streamline has been a trusted name in copper fittings for over 80 years, and this reducer reflects that heritage of precision manufacturing and consistent quality. Plumbers, pipefitters, and mechanical contractors rely on Mueller Streamline fittings for residential, commercial, and light industrial plumbing applications. The fitting weighs approximately 0.10 pounds and is a compact, durable component that integrates seamlessly into standard copper solder-joint assemblies. Whether you are roughing in a new system or modifying an existing one, the w01339 delivers the dimensional accuracy and material quality that experienced trade professionals depend on.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWrot copper construction provides a tight grain structure for strong, reliable solder joints in pressurized water systems\u003c\/li\u003e\n\u003cli\u003eFTG x C end configuration allows a 1-inch male solder fitting end to connect to a 1\/2-inch female solder cup, enabling smooth pipe diameter reduction\u003c\/li\u003e\n\u003cli\u003eMeets NSF 61G and multiple ASME standards including B16.18, B16.22, B16.24, and B16.50 for use in potable water supply applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Mueller Streamline w01339 wrot copper reducer fitting delivers proven solder-joint performance in a compact, standards-compliant design.
