Mueller Streamline w01124 Male Adapter C X Mpt 3/8 Inches X 1/2 Inches Wrot Copper Solder Fitting

Product Description

The Mueller Streamline W01124 is a wrot copper male adapter fitting with a Cup (C) solder-joint inlet and a Male Pipe Tapered (MPT) threaded outlet. It connects a 3/8 inch copper tube to a 1/2 inch male NPT threaded connection. Plumbers and pipefitters use this adapter to transition from soldered copper tubing to threaded pipe or fittings in potable water supply systems. The C x MPT configuration means one end accepts a copper tube for soldering while the other end threads directly into a female NPT fitting, valve, or fixture. This makes it a go-to fitting when connecting copper supply lines to angle stops, shutoff valves, or threaded iron or brass fittings. Mueller Streamline has manufactured copper solder-joint fittings for over 80 years and is a trusted name in residential, commercial, and industrial plumbing. Wrot copper is formed from wrought copper stock, which produces a dense, consistent grain structure. This results in a fitting that is stronger and more reliable than cast alternatives for pressurized water supply lines. The W01124 is rated for above-ground potable water service and meets NSF 61G requirements for contact with drinking water. It is manufactured to multiple ASME standards including B16.22 for wrought copper fittings and B1.20.1 for pipe threads. The fitting weighs just 0.09 pounds, making it easy to handle in tight spaces such as under sinks, inside walls, or in cramped mechanical rooms. HVAC technicians also use copper male adapters like this when connecting copper refrigerant or condensate lines to threaded components. Keeping this fitting on the truck or job site means fast, code-compliant transitions between copper tubing and threaded systems.

• Wrot copper construction provides a strong, dense fitting ideal for pressurized potable water supply systems
• C x MPT end configuration allows direct solder connection to 3/8 inch copper tube and threaded connection to 1/2 inch NPT female fittings
• Meets NSF 61G for potable water contact and multiple ASME standards for dimensional accuracy and thread compatibility

Product Highlights

The Mueller Streamline W01124 male adapter delivers a reliable, code-compliant transition from 3/8 inch soldered copper tube to 1/2 inch male NPT threads. It is built from wrot copper and certified for above-ground potable water service.
