Abstract
A sub connects a gun string to a hydraulically activated setting tool for setting an auxiliary tool in a well. The sub includes a housing that prevents a well fluid from entering inside the housing; a plug that covers a hole made in a wall of the housing; and an explosive mechanism located inside the housing and configured to break the plug to open the hole to achieve fluid communication between an outside and the inside of the sub.
