Compared with the prior art, the STANDARDS SCR urea tube quick connector fully utilizes the elasticity of the plastic ring and the rubber ring, and installs the sealing assembly between the stopper on the female connector and the step through hole, so that the male connector is inserted and removed during the insertion and removal process. The position of the seal assembly does not move, making the seal reliable. It is more reliable than the existing sound in the assembly factory to judge whether the sound is inserted or not. The snap-on pull-out design is more labor-saving than the transmission of the plastic ring by means of a finger. The waist groove of the fastener is simple and practical, and is convenient and flexible during the locking and relaxing process of the male connector.
