Propane Supply Acme Nuts

[Dutch]

I have been looking at getting some ACME nuts for members so that they can get rid of the wrench applied fittings to the typical 20 lb. cylinder.
I have come up against a bit of a quandary.
It appears that the classic BLACK version is good up to 80,000 BTUs and has a flow limiter that would restrict flow beyond that.
Then there is a GREEN unit which has similar limitations beyond 200,000 BTUs. mmmmmmmmmmmm
Since a typical BANJO burner is about 500,000 BTUs full on, it would appear that neither would work?
Any thoughts?
