The G70RP series connector is a quick connector with a rotating interface at the tail. The front end grabbing part retains the design of non-destructive inserts, and the tapered sealing ring seals. The tail rotating sleeve can realize 360 ° rotation, which is convenient for arranging test pipelines. The sleeve is left with a locking notch. After the connection is completed, it is turned to the notch to ensure that the connection will not be accidentally disconnected.
