Abstract

An end piece for a flexible connector comprises a sleeve defining the proximal end thereof. A length of corrugated tubing is extended into the sleeve and the sleeve is crimped thereby joining the length of corrugated tubing to the end piece. For high pressure applications a length of polymeric tubing, a length of mesh tubing, and an outer sleeve are positioned in a surrounding relationship to the sleeve of the end piece and the outer sleeve is crimped thereby securing the length of mesh tubing to the end piece.

Claims (20)

1. A method of manufacturing a flexible connector including the steps of:

providing a length of corrugated tubing comprising a plurality of grooves defining the corrugation thereof;

providing an end piece having a proximal end, the proximal end of the end piece comprising a sleeve;

the sleeve of the end piece comprising an interior surface having a circular groove formed therein;

providing an O-ring;

positioning the O-ring in one of the grooves of the length of corrugated tubing;

extending the distal end of the length of corrugated tubing into the sleeve and thereby positioning the O-ring in engagement with the circular groove formed in the interior surface sleeve;

providing a length of polymeric tubing;

positioning the length of polymeric tubing in a surrounding relationship with respect to the distal end of the length of corrugated tubing and the sleeve of the end piece;

providing a length of mesh tubing having a distal end;

positioning the length of mesh tubing in a surrounding relationship to the length of polymeric tubing and with the distal end thereof in alignment with the distal end of the length of corrugated tubing and with the sleeve of the end piece;

providing an outer sleeve;

positioning the outer sleeve in a surrounding relationship with the distal end of the length of mesh tubing; and

thereafter crimping the sleeve of the end piece and thereby securing the length of corrugated tubing to the end piece.

2. The method of manufacturing a flexible connector according to claim 1 wherein the corrugated tubing is stainless steel.

3. The method of manufacturing a flexible connector according to claim 1 wherein the corrugated tubing is bronze.

4. The method of manufacturing a flexible connector according to claim 1 wherein the corrugated tubing is a polymeric material.

5. The method of manufacturing a flexible connector according to claim 1 wherein the polymeric tubing is flexible.

6. The method of manufacturing a flexible connector according to claim 1 wherein the mesh tubing is stainless steel.

7. The method of manufacturing a flexible connector according to claim 1 wherein the mesh tubing is nylon.
