True... but irrelevant to my question.

Why don't you want it? It doesn't add much weight, and it gives you an easy adaptation to a tee fitting for the relief valve.

Removing a pre-installed fitting would be like changing the terminal screws on a Victor. Yeah, it's not precisely the original hardware, but from a safety and function perspective it hasn't changed.
The steel coupler pushes a few fittings and a gauge to a spot that's less accessible (and makes the gauge less readable) so it is handy to not have it in place.
The port in the compressor is 1/8NPT, so attaching normal hard-fittings and tees is the same as attaching to the steel part, it just fits into our robot a bit more easily.
