I am replacing my 9 year old gas dryer. I am considering replacing the flexible gas hookup when I replace the dryer. I was wondering whether that was recommended or is the lifetime of the hookup much longer? It has not been flexed more than once or twice in the past 9 years. I've never done a gas hookup before. Other than not smoking and turning off pilot lights, any other suggestions? Is anything used to seal the threads? I remember some discussion over the use of teflon tape with gas connections some time ago.
Thanks.
