Abstract
A fluid connection is formed between a tube for carrying fluid and a parent material having a surface wherein the fluid passes between the tube and the parent material. The connection has a first wall in the parent material defining a flow passage having a first diameter in the parent material for the fluid. A second wall is formed between the first wall and the surface of the parent material. Threads are formed in the parent material between the second wall and the surface of the parent material for engaging an insert. A tube having an end portion placed adjacent the second wall is used in the joint wherein the tube is sealed in the parent material between the first wall and the threads in the parent material. An insert engages the threads for maintaining the tube in a sealed condition.
