Abstract
A method for forming a flare in the end of a flexible tube comprises heating the end of the flexible tube to a near-melted state, inserting the end of the flexible tube into a flare-forming die (42) with a flare forming portion (62), and pressing a mandrel (51) into the end of the flexible tube, thereby pressure forming a flare in the end of the flexible tube.

7. The method of Claim 6, wherein the tube stop comprises a transitional slope of the mandrel.
8. The method of Claim 1 , comprising: pressing the mandrel into the end of the flexible tube up to a flare forming position, to form a final form of a flare in the end of the flexible tube in one pressure forming action.
9. The method of Claim 8, comprising: leaving the mandrel in the flare forming position for a time sufficient to form a flare that will retain a flared shape.
10. The method of Claim 8, comprising: leaving the mandrel in the flare forming position for at least about sixty seconds.
1 1. The method of Claim 1 , comprising: pressure forming a flare in the end of the flexible tube, wherein an inner profile of the flare matches an outer profile of a fitting adapted to be fitted to the end of the flexible tube.
12. A system for forming a flared end of a flexible tube, comprising: a heater comprising a contact heating structure with a contact heating surface for contacting and heating an entire circumference of an end of the tube; a flare forming die; and a mandrel.
13. The flare forming system of Claim 12, wherein the heater comprises a contact heating receptacle adapted for uniformly contact heating the circumference of the end of a flexible tube.
MENDED SHEET 1ABTaE W) Vf
