Step 2: Remove burrs.
Burrs can affect the air-tight seal of refrigerant piping connection. They must be completely removed.
1. Hold the pipe at a downward angle to prevent burrs from falling into the pipe.
2. Using a reamer or deburring tool, remove all burrs from the cut section of the pipe.

Step 3: Flare pipe ends
Proper flaring is essential to achieve an airtight seal.
1. After removing burrs from cut pipe, seal the ends with PVC tape to prevent foreign materials from
entering the pipe.
2. Sheath the pipe with insulating material.
3. Place flare nuts on both ends of pipe.
Make sure they are facing in the right direction, because you can’t put them on or change their
direction after flaring. See Fig. 7.3
