helping my dad redo his laundry room and we are moving the gas line for his dryer. the old line that still there has a bunch of reducer fittings below and above the floor and he wants to replace everything. I know you cant run flexible gas line up thru the floor, which is what he wanted to do. So now Im looking for the correct way. I found this Gastite pipe that has a flange built into it with threaded pipe on both sides of that flange. is this something i could use to route the gas up thru the floor? see link below. thank you for all that apply.
