发明名称 Bullthread
摘要 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.
