Mueller Streamline w01531 Copper Adapter Fitting Ftg X Fpt 1/2 Inches

Product Description

The Mueller Streamline w01531 is a wrot copper adapter fitting designed to connect a male solder fitting end (FTG) to a female pipe tapered thread (FPT/NPT) end, both in the 1/2 inch size. This type of adapter is a standard transition piece used in residential and commercial plumbing systems where copper tubing meets threaded pipe connections. Plumbers and pipefitters rely on this fitting to transition between soldered copper lines and threaded components such as valves, water heaters, pressure gauges, and supply line stops. The wrot copper construction provides excellent corrosion resistance and long-term durability in pressurized water systems. Wrot copper is produced by an extrusion or forging process that aligns the grain structure of the metal, resulting in higher strength and tighter dimensional tolerances compared to cast fittings. This makes it a preferred choice for tight-tolerance installations and high-cycle systems. The w01531 is rated for use in above-ground potable water supply systems, making it safe and code-compliant for domestic water applications. It meets NSF 61G certification, which verifies that the fitting material does not leach harmful substances into drinking water. The fitting also conforms to multiple ASME standards including B16.15, B16.18, B16.22, B16.24, B16.50, and B1.20.1, ensuring dimensional accuracy and compatibility with standard copper tube and NPT threaded pipe components. Mueller Streamline has been a trusted name in copper solder-joint fittings for over 80 years, and this adapter reflects the brand reputation for consistency and precision. At 0.11 pounds, it is lightweight and easy to handle during installation. Whether roughing in new construction or repairing an existing potable water system, this 1/2 inch FTG x FPT copper adapter is a reliable, code-compliant solution.
