Made to the highest quality standards, Jones Stephens' copper stub outs with open and closed ends for pressure testing are the professional, trusted choice for your installation. Install a stub out during the rough-in phase of your remodel or construction, and the exposed end will be ready for a connection to a fixture or device. These stub outs connect to ASTM F1960 (cold expansion style) PEX, are lead free, and are tested and listed by IAPMO for approval for use in drinking water services in the USA and Canada.
