Joint Construction, Connector Sleeve, A Coupling Assembly, and a Method for Preparation

Abstract

A connector sleeve for joining conduit, and a joint construction, and a coupling assembly for joining conduit; and a method for joining conduit using a coupling assembly.

1 . A method for coupling conduit sections, comprising;
 swaging an end of a first conduit section to form an enlarged diameter end;   coupling a connector sleeve within the enlarged diameter end of the first conduit section, the sleeve having a first end received within the enlarged diameter end of the first conduit section and an externally threaded second end defining an axial bore;   encircling an end of a second conduit section with an internally threaded annular gland nut and a compression washer;   inserting the end of the second conduit section into the axial bore; and   tightening the gland nut about the connector sleeve second end to compress the compression washer about the second conduit section thereby providing resistance to axial movement of the second conduit section relative to the first conduit section.
