NIBCO 3/4 in. x 1/2 in. Copper Press x Press Pressure Reducing Coupling

The NIBCO PressSystem reducing copper coupling 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 coupling has press connections. The fitting provides a method to connect a larger size to a smaller size tube.
