Abstract: A wellbore tool is provided that can withstand applied pressure tests without becoming hydraulically actuated. The wellbore tool includes a tubular housing including an inner bore; a tool mechanism responsive to fluid pressure; and an indexing mechanism that indexes responsive to tubing pressure cycles of at least an indexing pressure. The indexing mechanism is configured to activate the tool mechanism after a preset number of indexes. The wellbore tool can be pressure tested at pressures above an activation pressure without activating the tool mechanism.
