Patent ID: 8176612

Claim:
A method for making a high pressure connection for a well using a connector, wherein the method comprises the steps of: a. sliding an inverted jam nut onto a downstream end of a tube; b. sliding a nipple comprising a test port onto the tube, wherein the test port comprises a test port plug; c. sliding a first ferrule onto the tube adjacent the nipple; d. sliding a second ferrule onto the tube adjacent the inverted nut; e. inserting an upstream end of the tube into a female profile, wherein the first ferrule is adjacent the female profile; f. threadably engaging the nipple with the female profile while maintaining the first ferrule between the female profile and the nipple; g. threadably engaging the inverted jam nut with the nipple while maintaining the second ferrule between the inverted jam nut and the nipple; h. removing the test port plug; i. connecting a pressure generating device to the test port; j. applying a pressure from the pressure generating device through the test port, thereby compressing the second ferrule deforming the second ferrule into the inverted jam nut while deforming the second ferrule onto the tube forming a secondary seal, and thereby compressing the first ferrule deforming the first ferrule into the nipple while deforming the first ferrule onto the tube forming a primary seal; k. evaluating integrity of the primary seal and the secondary seal; l. bleeding the pressure; m. reinstalling the test port plug into the test port; and n. running the connector into the well.
