The NIBCO Press System® copper tailpiece features an inboard bead and EPDM O-ring. Simply applying pressure from a pressing tool tightens the O-ring onto the tube, ensuring a clean, watertight seal in seconds with no flame, solder or flux. The union has a press connection and a male NPT thread. It is used to allow repair to the line without damage between a press connection and threaded connection.
