16" for 3/8".
Torque for tube nuts is 40 to 65 lb.in. for 1/4" and 75 to 125 for 3/8" (for
5052-0) Any rigid pipe should have at least one bend in it and the flared
ends should mate to fittings before the nut is pulled down.

make a second copy of each section and hang it on the wall, than to
manhandle a replacement (heaven forfend) later?
