What is the manufacturing progress for AN fitting?
Different fittings have different manufacturing progresses. Let us take the most popular aluminum elbows AN fitting product (see picture below) in our factory to show the whole progress briefly.
First, prepare all loose components including the middle tube, tube ends, socket, nut, and lock wires.
Middle tube: Cut the aluminum tube to be the size and bend it at the required angle shape, so we have the middle tube ready.
Tube end parts: Manufacture the two aluminum 6061 tube end parts by using the CNC tuning method.
Socket and Nut: Manufacture the 2024 alloy socket and nut by using the CNC turning method.
Lock wires: Prepare the stainless steel lock wires by use cutting metal.
Secondly, weld the two tube end parts with the middle tube, make them be one piece firmly without any leakage problem.
After that, assemble the socket, nut, and lock wire on the middle tube, so the complete hose end is ready.
How to Install hose into AN Fittings?
For the tube and tube end assembly way, there might be more one. Below, we take the most suitable way that works in our factory, see the guild step by step.
Step1: Load the hose in the bench vise tightly with a tap at cutting point. Use a sharp cutting to cut the hose to length cleanly. You may need to clean up the end if need.
Step2: Hold the socket in the bench vise. Push the hose down into the socket with a twisting until the hose is positioned to the bottom.
Step3: Screw the socket onto the fitting. First, apply some lubricant to the threads to help with the screw work. After that, thread the socket down onto the fitting by hand as far as possible. At last, continue the thread work by using a standard AN wrench till the assembled fitting is firm enough.
Step4: Inspect the finished fitting and make sure there is no leakage under normal operating conditions.
Step5: Once the above fitting is done successfully, continue to complete the second side of the hose.
