snippet: The NIBCO® Press System reducing copper coupling features an inboard bead and yellow HNBR O-ring. Simply applying pressure from a pressing tool tightens the O-ring onto the tube, ensuring a clean, robust 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. NIBCO press fittings are the fastest, easiest way to join copper tubing systems. NIBCO® PressG fittings are designed to join with seamless copper water tube in residential and commercial gas and compressed air systems. The press fittings can also be installed underground. NIBCO® PressG fittings are user friendly, quick and easy to install. When properly crimped a unique "N" witness mark is clearly visible.
