The environment needs to be clean and must have free space. Put down the flaring tool kit along with clamps and cone tools.
Cut the Rubber Line
After placing the set up nicely, it is time to get started. Take the rubber line in hand and cut the line properly. Cut it precisely on the amount necessary. Take the cutter and place it on the rubber line.
Spin the cutter and repeat until it separates. Notice that a burr will form. After that, use the tool on the back of the cutter, “Deburring Tool.”
Use Deburring Tool
Put medium pressure in the deburring tool and spin it again and again on the tip of the rubber line. Keep the rotation on back and forth.
After that, finish up the line with a file and make it face downwards. It is necessary to remove any filings through this process.
Clean the Clamp
After the deburring tool, now is the time to use the clamp. To use a clamp, make sure it is clean enough.
Take a neat towel and clean the clamp up well. Jaws, surface, everything needs to be clean. This will tighten the clamp for better results.
Fitting on The Clamp
After cleaning up the clamp, you need to install the fitting first. How to do that? First, take the clamp and place the rubber line in it.
The clamp will show how much you exactly need. If you do that after the flare, you can’t get it on. Repeat the process if you mess it up. This will also cost time.
The Flaring Process
The side that you flare needs to be by the side of the clamp. The line should indicate the same thickness as the dye.
For the dye, there are many dyes out there. You need to find out which dye fits your line and measure it that wise. Tighten the clamp, and don’t let the line slip away.
This is a very important part of the rubber line. If you mess it up, then the process needs to repeat.
After you tighten the clamp, cut the line. Put oil to the end of the dye. Now use the cone tool and push the line to form it. The cone tool will sit on the backside of the dye. Tighten the cone tool until it stops.
