Today we will be showing you how to make a flare in a pipe to use a flare fitting whether it is for propane or an oil line like in this case.
First you will want to make sure the pipe is clean where you plan to make the flare. To clean the pipe we will use plumber mesh. Once we have the pipe clean we can take a pipe cutter and cut the pipe to make a nice clean cut take your time with this step as you don’t want to egg or oblong the pipe. If you do the flare nut will not slide onto the pipe.
Once we have the pipe cut we can slide the flare nut onto the pipe and push it far enough back to be out of the way. With the flare nut on the pipe we can install the flaring block onto the end of the pipe. You will slide it onto the pipe using the correct size hole for the pipe you are trying to flare. The beveled side should be towards the cut end of the pipe. Once you have the pipe in the correct hole we can flip the wing nut in position and tighten them both to hold the block onto the end of the pipe. The pipe should be a little passed flush on the block. You may want to take a flat screw driver and tighten them a little bit more to make sure the block doesn’t move.
Once we have the block tightened we can grab the other part of our flaring kit and slide that onto the block. Once it’s on the block we will turn it and move it into position so that the point of the cone will go into the center of the pipe. Once it’s aligned we can turn the handle to make the cone go into the pipe to make the flare.
Once we have it tightened down and you can’t turn it anymore we can now loosen it and then remove the flaring tool from the flaring block. With the flaring tool remove we can now loosen the two wing nuts and remove the flaring block. With the flaring block removed you should be able to see the flare at the end of the pipe. If you slide the flare nut to the end of the pipe you shouldn’t be able to remove the nut off the pipe.
Now that we have one side done we can repeat the process on the other side. First well take plumber mesh and clean the pipe where we plan to cut it. Next take the pipe cutter and cut the pipe back enough so we can fit the flare coupling in between the pipes.
Once we have the pipe cut to our desired length we can put the flaring block onto the end of the pipe and tighten the two wing nuts. Make sure the beveled part of the block is towards the cut end of the pipe and the pipe is sticking out of the block a little more than flush.
Once the flaring block is on the pipe we can grab the flaring tool and slide that onto the block and then align then cone with the pipe. Then tighten the handle all the way down till you can’t tighten it anymore then loosen it and remove the flaring tool. Next loosen the two wings nuts and remove the flaring block.
Now that we have both ends of the pipes flared we can grab the flare coupling and slide the flare nut to the end of the pipe and tighten it to the couple hand tight and then do the same with the other flare nut. Once we have both flare nuts hand tightened to the coupling you will need two pairs of pliers to tighten it. You will need one to hold the coupling and one to turn the flare nut. Once you have one flare nut tight move the pliers to the other nut and tighten it.
With both flare nuts tight you can turn on the propane tank and use mega bubbles to check for leaks. In this case we are going to turn on the valve on the bottom of the oil tank and check for leaks. With no leaks that’s it we just showed you how to make a flare in a pipe to use a flare fitting.
