    Description

    Our wellheads are dependable on the design excellence of Hercules™ casing and tubing heads, which are unmatched in the industry. Our Hercules patented slip design with positive mechanical stop limits slip travel and reduces stress in the wellhead body. The advanced top metal ring design reduces the gap between the top metal ring halves, preventing packing extrusion and minimizing water and dirt entrapment. Pressure assisted contoured packing assures positive pack-off with minimum compression. The slip design allows as much weight as the threaded connection will withstand without crushing the casing ID below API drift diameter.
