Abstract
A tube fitting for a tube end has a first coupling member and a second coupling member joined with the first coupling member. A tube gripping device is disposed between the first coupling member and the second coupling member such that assembly of the first coupling member with said second coupling member to a pulled-up condition causes the tube gripping device to be plastically deformed and swaged into the tube to grip and seal the tube. The first coupling member engages an internal surface of the second coupling member to provide an indication of completed pull-up.
Claims27
A tube fitting for a tube end, comprising:
- a first coupling member;
- a second coupling member joined with said first coupling member;
- a tube gripping device disposed between said first coupling member and said second coupling member such that assembly of said first coupling member with said second coupling member to a pulled-up condition causes said tube gripping device to be plastically deformed and swaged into the tube to grip and seal the tube;
- wherein the first coupling member directly contacts an internal surface of the second coupling member to provide an indication of completed pull-up.
A method of assembling a tube fitting, comprising:
- joining a first coupling member with a second coupling member such that a tube gripping device is disposed between said first coupling member and said second coupling member;
- engaging an internal surface of the second coupling member with the first coupling member to provide an indication of completed pull-up;
- wherein completed pull-up of said first coupling member with said second coupling member causes said tube gripping device to be plastically deformed and swaged into the tube to grip and seal the tube.
