I was wondering if anyone can help me with what size of stainless steel piping I need to use to ruffin my stove and dryer. 1/2 or 3/4.
Normally Chuck black pipe is used, then a flex-line is taken off the black iron pipe. You can get adapters from either 3/4" or 1/2" to make your connection. I would use what's there already if possible. Just make sure you use a NPT fitting onto the black pipe and then a flared fitting to make the flex line connection. If you need further help check out DanO's website www.appliance411.com. Use pipe dope on male threads only and you should have no problems.
