A compression coupling for a pipe or tube having improved uncoupling and recoupling capabilities. The coupling is of the type wherein a tube is received into a body portion and is attached thereto by the action of one or more ring-like ferrules which are wedged between the tube and the body by a coupling nut. The improvement is principally in the shape of the tube receiving bore in the body which is made with angularly positioned tube sizing and tube braking surfaces. This shaping of the bore causes the tube when initially attached to and seated on the body to have a selective reshaping which facilitates tube removal and reinsertion regardless of dimensional variations in the body and tube sizes. |
