Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Reserved for B30:

The same as my B35 but I need to transfer my heater to the B30, I only have the one.  Also, the O-rings are a wee to big for the sight glass, I expect the glass is a replacement.  What I did is double them up, so two O-rings for each side.  This seemed to have allowed the rings to compress and when I "blow" into the tank no air is getting past the seals.  Granted me blowing into the take isn't a lot of pressure!
