DBT-Series Bolt Tensioners

The DBT-Series Hydraulic Bolt Tensioners will ensure uniformed gasket compression. Compression is essential for the integrity of critical bolted flange connections. Unlike a torque wrench, the DBT-Series Bolt Tensioners are capable of tightening more than one bolt at a time and can apply a consistent torque via direct axial stretching to any given number of bolts simultaneously. These tensioners have been designed to fit all standard ANSI & API flanges with quick release bridge and hexagon socket for fast change over. There are 10 load cells from M20 to M150 or 3/4″ to 5-3/4″ and they are light and easily handled.





Removable & Rotational Bridge

  • The bridge is removable and rotational with a full bridge window to simplify positioning.

Dual Ports

  • Dual ports allow quick coupling of multiple tools.

Electroless Nickel Plated

  • All cylinders are electroless nickel plated for extra protection and are easily maintained.

Anti-Slip Grip

  • The knurled finish provides anti-slip grip for better handling.

Bridge Size Standard

  • The bridge size is standard for each load cell.

Tommy Bar

  • A tommy bar is supplied to enable easy tightening or loosening of the thread adaptor or hex socket.
