GRIPPER TYPE TOOLS

The Double Block and Bleed Gripper Tools are designed to provide an isolation barrier on localized field repair and modifications. The safety jaws allow the end user to isolate, monitor, and vent hydrocarbon vapors to a safe area when performing welded connections while giving them the assurance that the safety jaws are rated for 1,500 PSI in case of a primary isolation failure. Superior’s plug incorporates unique gripping feature geometry that make it the most application-efficient tool on the market, while keeping safety the number one goal.
