I have a new Gas Stove. The new stove has 1 /2" male connector for the supply line, and it came with a flexible supply line that is 1/2" female on both ends.
My old stove has a 5/8" male connector for the supply line, and a flexible supply line that is 5/8" female on both ends.
The pipe coming out of the floor has a 5/8" male end on it.
So it seems like a simple fix - either:
a) Find a fitting to take the 5/8" male end coming out of the floor down to a 1/2" male end, and then use the 1/2" flexible supply line.
b) Find a fitting to take the 5/8" female end coming out of the flexible supply line down to a 1/2" female end, and then hook it to the stove.
So I have been to two hardware stores and surfed the Internet. It seems like this 5/8" setup never existed. No 5/8" flexible supply lines are offered for sale, and nothing to adapt a 5/8" male or female to a 1/2" male or female seems to exist.
So right now, I am in the Twilight Zone, and the guy I gave my old stove to likely is as well.
