A connector for use in combination with piping to transform plumbing pipe stub outs to re-sealable leak-proof open or closed stub outs. The connector is an elongated hollow cylindrical brass fitting having first and second ends wherein the first end slides into an open end of a copper stub out pipe and securely attached thereto. The second end of the elongated hollow cylindrical brass fitting has a threaded interior surface that is configured as a female threaded receptor to engage a male threaded plug. The threaded plug removably engages the second end of the elongated hollow cylindrical brass fitting by screwing into or out of the elongated hollow cylindrical brass fitting. The insertion and removal of the threaded plug allows for the drain of debris, pressure testing and inspection of the copper piping throughout a newly constructed building without the traditional cutting and recapping now permanently closed stub outs which may have been bullet stub outs or stub outs that have been soldered closed.
A stub out adapter that is connect to an open ended piping assembly stub out to allow the stub out to be removably sealed, the adapter comprising:
An elongated hollow cylindrical stub out having first and second ends wherein said first end has threads on a portion of its interior surface that allow said stub out to be plugged with a threaded plug that engages said first end of said stub out by screwing the plug into said first end.
A stub out having first and second ends wherein said first end has threads on a portion of its exterior surface that allow said stub out to be capped with a threaded cap that engages said first end of said stub out by screwing the cap onto said first end.
