Things You'll Need:
- Copper compression fitting
- Flaring tool
- Adjustable wrench
-
Step 1
Take the nut off of the compression fitting, and slide it on to the copper tube. This is the compression nut that will tighten the joint in conjunction with the ferrule, which is also called an "olive" or a "sleeve".
-
Step 2
Slide the ferrule on to the copper tube, then use the flaring tool to flare the end of the tube just enough to keep the ferrule from sliding off.
-
Step 3
Use steel wool to remove burrs from the end of the copper pipe. Wrap PTFE Teflon pipe sealing tape around the threads of the threaded end of the compression fitting. Slip the flared end of the tube into the compression fitting, slide the ferrule and the nut to the compression fitting, fit the nut over the threaded end of the compression fitting, and tighten the nut until it is "hand tight."
-
Step 4
Repeat the process with the other pipe segment: Remove the compression nut from the fitting, slip the nut and ferrule on to the pipe, flare the pipe, de-burr the pipe end, wrap the threads of the compression fitting, slide the pipe into the compression fitting, and hand-tighten the compression nut.
-
Step 5
Use the adjustable wrench to tighten the compression nuts just enough so there is no leakage. If a leak develops later, it can easily be repaired by tightening the compression nut some more.
