ABSTRACT:
A pipe connector comprises mainly a main body, a threaded cap, and a rubber washer. It is further provided therein with a circular bowlike curved flange and means to prevent leak. In the process of joining the connector with a pipe, the connection head is made to engage securely with pipe by means of tightening the threaded cap to engage the main body so as to press the circular bowlike flange to engage securely the pipe in a leakproof manner and in such a way that it prevents the connection head from disengaging the pipe under high pressure.
