I am building a stationary mill engine with a 1/4" copper steam feed.
I want to fit a displacement lubricator with a single pipe fitting. the only ones I can find have 1/4 x 40 fitting for 1/8" pipe. The way round this, I suppose, is to fit a reducing tee in the 1/4" pipe but I can't find one of those either.
I'm sure others out there have fitted lubricators on 1/4" pipe. Did you find a suitable lubricator or did you get round the problem somehow?
