How to Install the Metric Thread Bite Type Tube Fitting?

1.Sawing the seamless steel pipe in a proper length, and to remove metal burr. The pipe end should be perpendicular to the axis, the angle tolerance is not greater than 0.5 °. If you need to bend the pipe, then the straight length that from pipe end to curved part can not be less than three times of the nut length.

2.Seting nut and bite type tube fitting on the seamless steel tubes. Pay attention to the direction of the nut and ferrule, not installed backwards.

3.Lubricating the pre-assembled adapter fitting thread and ferrule, and to entirely insert the tube into the metric thread bite type tube fitting, then to tighten the nut by hand until ferrule stucking the tube, this pressure point can be felt with the increasing of tightening torque, finally to further tighten the compression nut 1/2 turn after reaching the pressure point.

4.Removing the pre-assembled adapter body, to check the embedding of ferrule blade edge, the obvious protrusion must fill the ferrule end space.

5.Final installation, the metric thread bite type tube fitting thread coated with lubricating oil, to tighten the compression nut until feeling the increasing of the tightening force, still to tighten 1/2 turn.
