Abstract
A pipe coupling device includes an externally threaded first tubular coupling element engaged by an internally threaded second tubular element provided with an outer axially bored end wall and an annular nylon sealing member entrapped between the second element end wall and the confronting end face of the first element. The sealing member includes a tubular body section and a reversely curled outer end flange forming a cuff. In application, the second element is slipped onto the end of a pipe, the sealing member is then positioned on the pipe and the second element slid down to overlie the sealing member, then the first element is slipped onto the pipe, and the coupling elements are screw tightened to longitudinally and radially compress the sealing member into pressure engagement with the faces of the annular cavity delineated by the coupling elements and pipe, wherein a groove is formed on the pipe to lock the coupling in place on the pipe.
