Abstract
Abstract A fluid connection is formed between a tube (40) for carrying fluid and a parent material (14) having a surface (56) wherein the fluid passes between the tube (40) and the parent material (14). The connection has a first wall (50) in the parent material (14) defining a flow passage (52) having a first diameter in the parent material (14) for the fluid. A second wall (54) is formed between the first wall (50) and the surface (56) of the parent material (14). Threads (66) are formed in the parent material (14) between the second wall (54) and the surface (56) of the parent material (14) for engaging an insert (68). A tube (40) having an end portion (76) placed adjacent the second wall (54) is used in the joint wherein the tube (40) is sealed in the parent material (14) between the first wall (50) and the threads (66) in the parent material (14). The insert (68) engaging the threads (66) maintains the tube (40) in a sealed condition.

Claim 1
Independent Claim
246 words
A connector for connecting a tube, for carrying fluid, to an internally threaded parent material using a tube having an external flanged portion around an end portion of the tube to be connected to the parent material, the connector comprising: a first member comprising: generally annular body means having upper and lower portions for encircling at least part of a tube, external threads on only the lower portion of the body means, first means on the upper portion of the body means for engaging a second member, a first substantially uniform surface on an interior portion of at least the upper portion of the body means for encircling the tube, and a second surface in the lower portion of the body means separate from the first substantially uniform surface facing at least partly in a direction away from the upper portion of the body means for contacting an external flanged portion on a tube; and a second member engaging and axially moveable relative to the first member and comprising second means on an interior portion of the second member for engaging the engaging means on the upper portion of the body means of the first member for substantially preventing relative rotational movement therebetween, and means on an external surface of the second member for engaging the parent material when the first member is threaded into the parent material, and means for engagement with a removal tool for moving the second member away from the first member.
Claim 2
Dependent Claim
246 words
A connector for connecting a tube, for carrying fluid, to an internally threaded parent material using a tube having an external flanged portion around an end portion of the tube to be connected to the parent material, the connector comprising: a first member comprising: generally annular body means having upper and lower portions for encircling at least part of a tube, external threads on only the lower portion of the body means, first means on the upper portion of the body means for engaging a second member, a first substantially uniform surface on an interior portion of at least the upper portion of the body means for encircling the tube, and a second surface in the lower portion of the body means separate from the first substantially uniform surface facing at least partly in a direction away from the upper portion of the body means for contacting an external flanged portion on a tube; and a second member engaging and axially moveable relative to the first member and comprising second means on an interior portion of the second member for engaging the engaging means on the upper portion of the body means of the first member for substantially preventing relative rotational movement therebetween, and means on an external surface of the second member for engaging the parent material when the first member is threaded into the parent material, and means for engagement with a removal tool for moving the second member away from the first member.
