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 pipe with insulating material.
3. Place flare nuts on both ends of the pipe. Make sure they are facing in the right direction as
you cannot change their orientation after flaring.

flare form in accordance with the pipe extension table.
