That might be the case on a Navy ship boiler system where the
steam is being used for very sensitive applications like the
expanding steam turbine turning gear for propulsion... But in
a home or commercial heating system using steam -- there is
a lot more harmful stuff in the _water_ than a bit of grease getting
past a failed gasket on a valve at a radiator...


I've lived in 3 homes with steam heat, replaced a few valves and complete
radiators in that time, as well as similar chores for neighbors, also helped
install a new boiler. What kind of residential radiator valve uses a gasket?
I've never seen one that did.
