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.
