Introducing
The reverse connection joint is also known as a reverse connection spear, which can replace the male cone for fishing or reverse connection operations when dealing with stuck pipe accidents. If the fish is stuck or cannot be reversed, it can be released from the reverse connection joint and the fishing tool can be retrieved.
