• Sorry for keep asking these stupid questions. My Steam Wagon probably needs new washers on the safety valve (water filler) and the whistle. The safety valve looks to be 1/4" and might be a rubber 'O' ring. The whistle doesn't look as if it has a metal washer which doesn't seem right to me. Looking at ebay the washers all seem to  be fibre. Is this correct?
  
  Thanks

• Hi Brian, there's no stupid questions mate....ask away!
  
  Yes, they are some sort of fibre washers.
  
  I have used O rings, and also cut some out of gasket material (from auto shops) and also used leather.
  
  They are easy to make if you have some old leather from a belt or a pair of boots etc laying around the house.
  
  If you use an O ring, use the tightest fitting one that you have.

• Thanks for that, I assume you mean the steam whistle as well?

  Yes Brian, same for the whistle as well.
  
  It works out a lot cheaper making your own.

• Rubber o-rings do work but they seem to fail on a lot of loosening and retightening. I find that dark gray automotive high temperature gasket paper works the best. I have a leather punch with different sizes so I can make a nice fit.
