FT-6™ / FT-8™: Upset | Gas Tight | Two-Step

Overview

Built for the Field. Proven Around the World.
Fermata® FT-6™ / FT-8™ Two-Step Connection

Designed to meet the demands of rugged, high-pressure operations, the FT-6™ / FT-8™ is a globally trusted two-step integral upset connection. Whether milling, fishing, or performing other heavy-duty workstring operations, this connection delivers reliable, repeatable performance.

  • Metal-to-Metal Gas-Tight Seal
    Dual energized metal-to-metal seals—positioned both internally and externally to the threads—ensure gas-tight integrity, even under extreme pressure.
  • Streamlined Outer and Inner Diameters
    Matching box outer diameters minimize hang-ups, while a continuous recess-free bore ID supports smooth flow.
  • Reliable, Repeatable Make-Up
    Two-step threading enables deep stabbing and stable alignment during make-up, enhancing efficiency and reducing operational risk.
  • Anti-Galling Design
    Non-interference thread geometry supports routine, reliable make-up while minimizing galling.
  • Proven Field Performance
    Backed by decades of successful deployment across global basins, this two-step design is a trusted standard for durability and performance.
  • High Torque Capacity
    An external negative torque shoulder and intermediate stop provide a large torque area, enabling the connection to handle high torsional loads.
  • Slim OD Clearance Options
    Optional slim OD designs are available for applications requiring reduced clearance without compromising connection integrity.
