Streamline 7054 1-1/2" DWV Adapter
The Streamline 7054 is a cast brass DWV adapter connecting 1-1/2 inch copper tube to male NPT threads. It serves plumbers and maintenance teams joining copper drainage, waste or vent lines to threaded pipe or equipment in residential and commercial systems.
Sweat-to-thread installation notes
The cup end accepts 1-1/2 inch copper tube with a 1-5/8 inch outer diameter for sweat soldering. The MNPT end threads into 1-1/2 inch female fittings. No center stop is included, so the tube can slide fully through; installers must gauge insertion depth themselves. Overheating during soldering can damage threads or distort the brass body.
Pressure and temperature headroom
Rated for 408 psi at 100 degrees F and 250 degrees F maximum operating temperature, the adapter handles typical DWV pressures with ample margin. It is not suited for high-pressure supply lines exceeding the rated pressure or for continuous service above the temperature limit. Buyers needing a center stop or a different connection type must select another fitting.

Questions about this item
How can I confirm the 1-1/2" copper sweat joint is leak-free after soldering?
Pressurise the line up to 408 psi at 100 °F and inspect the cup connection for drips; the straight adapter has no centre stop so flow should be unobstructed.
What comes with the Streamline 7054 adapter and what must I supply?
The box contains only the cast brass DWV adapter; you must provide 1-1/2" copper tube, solder, flux and 1-1/2" MNPT pipe or fittings for the threaded side.
Which version of the Streamline 7054 should I choose for a 1-1/2" copper-to-MNPT transition?
This single model is a straight 1-1/2" C × MNPT adapter rated 408 psi at 100 °F and 250 °F max; select it when those exact sizes and pressure limits match your DWV system.
