Abstract
A pipe connector comprises an internally threaded female member and an externally threaded male member for threaded engagement in the female member. When the members are fully engaged together, an axially and radially directed surface at the free end of one of the members, e.g. the male member, is abutted against a corresponding surface on the other member, e.g. the female member. The surface comprises radially inwardly and outwardly curved surface portions which are relatively dimensioned to be a radial force fit such as to cause deflection of the end portion of the free end of the male member away from the female member as the members are brought into full engagement to bring the surfaces into full engagement.
