I'm not an expert at gladhands, but looking at the details at NAPA on line yields some worthwhile information. The ones on my Deuce look more like the 1145x and 1146x series of glandhands; the 1143x are the flexible spring loaded type which I think are used on trailers, not on tractors/trucks. The 1145x series have a full face seal and are not filtered, the 1146x series has a Protect-O seal and are filtered. The individual numbers within the series identify whether the gladhand is plain or color coded (blue for service, red for emergency).
I suspect the seal types are interchangeable, otherwise it would really screw up the trucking industry. The 1146x series are probably a "premium" line. I would expect the 1145x are closest to what comes on the Deuce, specifically the MBI11450 in plain finish unless you have a pressing urge to switch to color coded gladhands. The only spec not given in NAPAs catalog is the pipe thread size, maybe they are all the same? I would think the MBI11450 should work out OK for you.
