Not sure how you did this. The three-way (tee) and 4-way I installed are the
same length, so no re-bending would be required.
3/8" copper lines are still 'modern' and the best bet and recommendation for
this application. If you're worried about flares, have the lines made by a
shop or buy a flaring too and a little extra tubing and practice. There is
only one line to make, the stove line. Flare the stove end, connect, then
bend near to the tee, cut, and flare again. Don't forget to slide the nuts
on first.
