# Low Profile Wrench Overview

The Torcflex low profile wrench (TFX) is a professional hydraulic power tool that is designed to exert torque on industrial fasteners to make sure of correct tightening or loosening of an industrial bolted connection. The tool uses a double acting hydraulic cylinder to transfer linear force into rotation torque through a ratchet mechanism. The torque is controlled by adjusting the pressure applied to the hydraulic cylinder.

The tool includes the following main components:

A | Swivel manifold | A swivel manifold with hydraulic couplings to allow connection to an appropriate hydraulic power supply.
B | Ratchet link | A ratchet link which provides the hexagonal drive. Atlas Copco provides several optional ratchet links for each powerhead model, so the hexagon size can be changed.
C | Hexagon drive | The hexagon drive is the functional part to apply torque for the ratchet link.
D | Retained pin | A retained pin for connecting the powerhead to the ratchet link.
E | Reaction arm | A fixed reaction arm to absorb the reaction force generated during tool operation.
F | Powerhead | A powerhead which is the hydraulic element of the tool.
