ABSTRACT:
A small-diameter pipe connector comprises a connector body and a socket body. The connector body has a front cylindrical portion and a rear lock portion and is formed therein with an axial through hole, a small-diameter chamber, and a large-diameter chamber. The socket body has a plurality of resilient pawls. A seal ring is fitted in the small-diameter chamber. A bush is disposed in the rear of the seal ring. A spring is provided such that an expanded portion of a pipe inserted in the small-diameter and large-diameter chambers is pushed against the resilient pawls. Therefore, the pipe connected in the connector does not shift axially and the seal ring wears little even under vibration conditions.
