   CP74 NOTE: The CP74 Series products operate slightly different from traditional dry break couplings. When making a
   connection with no pressure on the coupler and up to 3625 psi (250 bar) 172.4on2500  the nipple, a slight pause during connections is
   required to allow trapped pressure to vent to the coupler before completing the connection. Partial connection followed by
   disconnection may result in damage to the coupling.                    189.62750
