It is important to observe the positive engagement of plug-type couplings and the secure tightening of screw-type couplings to the limit stop of the thread. Forced or improper separation will result in malfunction of the coupling. Series FF-19 § BG 4 § Nominal Size 19 Port A Dimensions Female Body Weight Male Tip Weight ( mm / in ) ( kg /lbs )ca.
