I am curious to see as to why connecting the JBJ manifold to a ma957 shouldn't be done. Does Milwaukee make a similiar manifold that would help out individuals who are looking to do a similiar concept with a milwuakee setup? Has anyone tried to modify a ma957 with the splitter that is shown?Robert Hudson said:I was surprised to learn that Milwaukee says it should not be done...I don't see why not. It shouldn't be any different than any other regulator. I do understand though how that would void the warranty. That is completely understandable.
