Exclamation Flare fitting leak


I just got a new gas dryer and made some changes to the gas hook-up. I had 3 feet of 3/8 copper coiled up before going right in to the old dryer. I shortened it up to where it comes up from the basement and added a flare fitting so I could use a 48 flex line. I went Lowes and the guy sold me all the fittings and a new flare tool. My problem is I am on my 3rd try and am still getting leakage around the flare nut. I have to keep shutting the gas off under the dryer in the basement.
I am hoping someone can tell me what I might be doing wrong with the (I used no tape!)flare fitting?

Thanks,
Brian in MI

Flaring properly requires to use a sharp tubing cutter and tighten er down and cut slowly to not cave in the tubing as you go, as that makes flare more thick and suseptible for causing splits in the flare.

You also need to know how far to extrend the tubing through the flaring tool so the flare size winds up right, so that it fits in the flare nut good. Not too big, and not too small. Practice on scrap pieces.

Also, after you cut the tubing, you need to ream the inside of the pipe wall at the end, to thin out the thickened copper, from when you cut it. This step is often forgotten, or not known, by the novice. Flaring tools often even have that triangular-shaped reamer built onto the side of it. Even a jack knife scraped around the inside of the end can work.

If you do these things, then when you flare, the flare will mushroom out to the proper size without getting cracks in it and it should not leak.

................

I've mastered the process, so I know.

why not make this a legal installation and use black steel pipe to bring the line throught the floor and install a new gas valve behind the dryer and use the flex line ?

most all codes require the gas valve for an appliance to be installed with in arms reach of the appliance or at least in the same room on the same floor level as the appliance

Copper permitted

Thanks for the replies! We are permitted here to use the copper but I believe the builder should have run the pipe up to the dryer. If for some reason I can't get the fitting to stop leaking I may look into running pipe.

Thanks,

Thumbs up Got it

Thanks again after my 4th try no leaks! Is it possible I did not tighten the other tries enough? I gave this one an extra half turn!
