Based on the GDC's response to 2014 Q325, I think the hose AND the check valve that come from the manufacturer should be considered parts of the compressor, and therefore required per R65. Of course my opinion is worthless at inspection.

Eagerly awaiting the GDC's word on 2015 Q360.

Yup, that was me asking... I saw them answer a question that check valves are illegal (which was expected), but wanted to make sure there was another answer directly applicable to the compressor we're using so an overzealous inspector didn't point to that Q&A and make our whole system worthless. I can't overturn inspectors when dealing with my own team
