Teflon Tape on Flared fittings
This past week a friend of mine asked me to connect the gas line of her new gas dryer since the company delivering it does not do this anymore. I had hooked up my gas oven a couple of weeks ago and saw that a number of forum discussions indicated that you should not use Teflon tape on the flared ending of the flexible pipe.
Now the fun begins, when I arrived to help her out, everyone including the delivery guy, said I needed to use Teflon tape everywhere including the flared endings.
To make a long story short, over my concerns the delivery guy ended up connecting the line using either Teflon (gas) tape or pipe dope on the flared endings.
Am I wrong about the this matter and should she have any concerns about this? Thanks
