ABSTRACT:
There has been provided a coupler for joining lengths of concentric pipe. A sleeve member receives the pipes in spaced relation therein, with an end of the concentric inner pipe forward of the end of the outer pipe. A forward annular flange portion of said sleeve member is concentric with the pipes and extends radially inward as well as outward of the sleeve member. A rearward face of said flange portion faces the forward end of the outer pipe and is spaced away therefrom by a selected length of said tail portion forming an annular groove bounded by the outer pipe end and inner wall of said tail portion of the selected length and the rear face of the flanged portion. A compressible O-ring type elastomer seal is disposed in the annular groove and extends radially inward of said outer pipe. A gasket is concentrically sleeved between said O-ring seal and outer wall of the inner pipe. In compression, the O-ring seal and gasket form a circumferential seal about the inner pipe.
