Preparing the copper

Then, you can deburr the copper. Again, make sure you keep the end of the tubing facing down as you deburr so that the burr and any copper shavings fall out of the tube, not into it. There may be times when you can’t deburr copper in the downward position because of the way it’s attached to the system. If you can’t bend the copper downward, you may attempt to deburr the copper and then use a refrigerant line cleaner to send a foam pig

As with brazing, you also have to make sure your copper is clean, cut squarely, and ready for flaring before you actually make a flare. The first thing you’ll want to do is make sure the copper is squarely cut. If you need to cut the copper, clean it first. I don’t trust factory - made flares and don’t recommend you do it either, so I typically clean the copper past the flare and cut it off to start fresh.
