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

Wanted to share an update with my Dolly 364/1.     The pressure guage that was original to it had broke and was leaking steam.  I removed it altogether, and found the union to be leaking as well. Removed that, and found it to be metric M7x1.0.

Instead of that, I used a Marklin whistle with an O ring to make a seal, and I’m happy to announce it finally has no more leaks.   All fittings have rubber O rings as well.  The boiler doesn’t drink water as fast now, and has SO much more power.  In fact at times it is too much power!   None the less I am so happy with this.
