      Hi Gary,
      I use cork on my boiler, but it's a small cork (wine bottle) that the
      thermometer sticks through ( the cork will blow out if there's a
      pressure problem, Hopefully). I have to replace it now and then, it
      turns nasty where in contact with the steam. HTH
      Tip one, Morgan
