Hi Charlie

What material are the bushes in your boiler made from ?

Is it a commercially produced boiler ? Does the maker have a view ?

Sorry for all the Questions but it help you getting an answer 😀

Hi Ray it is a bushing from Clevedon steam

Hi.Charlie, personally I wouldn't use stainless on the steam side of a boiler, at higher pressures and temperature it is too unpredictable. Stainless is not allowed on full size engines or larger scale models either as fixings or steam fittings.

These days you need a good quality gun metal, a zinc free brass.

Hope this helps.

Eddie.

Hi Charlie,

I would agree with Eddie as he is a very experienced steam man, my only suggestion would be the use of PTFE tape round your stainless fittings thread and create a barrier and seal ??
