This adapter connects a 3\/4-inch cup end (C) on one side to a 1\/2-inch male pipe tapered thread (MPT) on the other. The cup end accepts a standard solder joint connection, while the male NPT thread end connects directly to female-threaded fittings, valves, or equipment. This transition style is one of the most common in residential and commercial plumbing work, making the w01147 a reliable go-to fitting for plumbers, pipefitters, and mechanical contractors.\u003c\/p\u003e\u003cp\u003eWrot copper fittings are manufactured by a wrought process that produces a dense, uniform grain structure. This results in a fitting with consistent wall thickness and high resistance to corrosion, scale, and pressure fluctuations. Copper is naturally compatible with potable water systems and does not leach harmful materials into the water supply. The w01147 meets NSF 61G requirements, confirming it is safe for drinking water contact. It also conforms to multiple ASME standards including B16.22, B16.15, B16.18, B16.24, B16.50, and B1.20.1, which govern dimensions, tolerances, and pressure ratings for copper and bronze solder-joint and threaded fittings.\u003c\/p\u003e\u003cp\u003eThis fitting weighs 0.12 pounds and is compact enough for tight spaces in wall cavities, mechanical rooms, or under-sink installations. It is well suited for connecting copper supply lines to threaded valves, stop valves, water heater connections, and fixture supply lines. Plumbers working on new construction, remodel, or service repair jobs will find this adapter practical and straightforward to install using standard soldering techniques and pipe thread sealant on the NPT end.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e3\/4-inch cup (C) solder end transitions to 1\/2-inch male pipe tapered thread (MPT\/NPT) for easy copper-to-threaded connections\u003c\/li\u003e\n\u003cli\u003eWrot copper construction meets NSF 61G for safe use in potable drinking water supply systems\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B16.22, B16.15, B16.18, B16.24, B16.50, and B1.20.1 standards for dimensional accuracy and performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Mueller Streamline w01147 male adapter delivers a dependable solder-to-thread transition in a compact wrot copper body rated for potable water service.
