ROHRVERBINDER

摘要

A connector, for example for connecting pipe sections, comprises a female member having threaded internal circumferential surfaces at each end, for engagement with a pair of male members each of which is provided with a threaded external circumferential surface. Each male member is provided with an annular nose having an axially directed primary sealing surface for sealing abutment with the primary sealing surface of the other male member, and a circumferential secondary sealing surface for sealing against a secondary sealing surface on the female member. The sealing surfaces being initially shaped so that when the noses are initially brought into contact there are progressively widening axial and radial gaps therebetween which are closed by deformation of the noses when the members are fully engaged together.
