It might be, the mechanic I barrowed it from uses it all the time at the dealership, it has two sizes of threads (I guess the most common sizes). It seems to be based on the same principle of the single hose model. Seems simple to make, all that is requires is machining and tapping a block. Picture on left is from the 'net, the one on the right with the 4 black hoses is the tool he let me use.
