The NIBCO® Press System® has taken press technology to a new level in leak detection, according to the manufacturer. The new PC585-70 cast bronze ball valve by NIBCO features a new design that allows a leak to occur during testing, if the press connection is not properly crimped. Other NIBCO® Press System® fittings and valves will feature this new leak detection technology using a phased-in approach. The NIBCO® Press System® ball valve is user friendly, quick and easy to install. The ball valve features threaded-in female press-to-connect end connections with an inboard bead and interface O-rings for fast and easy connection to the piping system. Properly applying pressure from a press-fit tool tightens the O-ring onto the tube, ensuring a clean, permanent, watertight seal in seconds, with no flame, solder or flux. When properly crimped a unique “N” witness mark is clearly visible.
