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

I use PMR unions on dedicated hard lines for several engines, others I can use a rubber hose with a PMR union on one end.  All of the hard lines are bent to perfectly connect up to the steam supply. I use slip on rubber hoses for all the exhaust lines .  As I wrote earlier, I have another 100% PMR steam plant with a vertical boiler and a dedicated no.3 engine , with a station that accepts these same stand alone engines perfectly .  It took a bit of planning and several dollars worth of PMR fittings .
