The MUELLER STREAMLINE ADP00349 is a wrot copper male adapter designed to connect a sweat solder fitting end to a male threaded pipe connection. With a 0.50 inch fitting (FTG) end and a 0.38 inch male NPTE thread, this adapter transitions between copper tubing and threaded pipe systems. At 3 inches in actual length, it provides a compact, reliable connection point in tight spaces. Installed by licensed plumbers and pipefitters, this adapter is appropriate for potable water, HVAC piping, and general plumbing distribution systems.
This adapter suits residential and light commercial plumbing applications where a copper sweat connection must terminate into a male threaded joint. Typical installations include connecting copper supply lines to threaded valves, fittings, or equipment ports. The wrot copper construction meets the demands of standard domestic water supply and hydronic piping configurations where a durable, soldered transition is required.
Designed as an OEM-style replacement or new-installation fitting for residential and commercial copper plumbing systems using 0.50 inch FTG sweat connections transitioning to 0.38 inch male NPTE threaded ports.
Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing codes. Shut off the water supply and depressurize the line before soldering. Clean and flux both the tube end and the fitting socket thoroughly before applying heat and solder to ensure a leak-free joint. Allow the joint to cool completely before restoring system pressure.
