These couplings, sharing the same internal design of traditional inserts for Multifaster, can be installed into low thickness plates or housings and are particularly recommended to manage the automatic connection and disconnection of hydraulic lines on compact CE machinery (e.g.: machine – arm or arm-tool connection). Depending on the size (3/8″ or 1/2″), their counterpart mates must be selected among the list of KIT3FNP38… or KIT3FNP12… part numbers (couplings for Multifaster). Connection under working pressure is possible thanks to the pressure relief system contained into male couplings.
