How to install compression fittings?

Many customers do not know how to install the compression fittings, in this article , it will introduce how to install the compression fitting :
1. Saw the appropriate length of seamless steel pipe to remove port burrs. The end face of the pipe should be perpendicular to the axis, and the angle tolerance should not be greater than 0.5 degrees. If the pipe needs to be bent, the length of the straight segment from the end face of the pipe to the bend must not be less than three times the length of the nut.
2. Put the nut and ferrule on the seamless tube, pay attention to the direction of the nut and ferrule, and do not install it in reverse.
3. Apply lubricating oil to the threads and ferrules of the pre-assembled fitting body, insert the pipe into the fitting body, the pipe must be inserted to the end, and tighten the nut by hand.
4. Tighten the nut until the ferrule jams the tube, this turning point can be felt by the increase in tightening torque.
5. After reaching the pressure point, tighten the hold-down nut for 1/2 turn.
6. Remove the pre-assembled fitting body and check the insertion of the ferrule edge, the visible protrusion band must fill the space on the ferrule endface. The ferrule can be rotated slightly, but not axially.
7. For final installation, lubricate the joint body and threads in the actual installation, and tighten the compression nut with it until the tightening force can be felt, and then tighten it for 1/2 turn to complete the installation.
