Expert Reply:

The hose and fittings sizes are standardized for RV's. Therefore, what you have is going to be a type 1 to either a 1/4" NPT or 1/4" Male Inverter Flare. If you have the former I recommend part # 100473-12 or part # 37207-30715 if you have the latter. That said, I get why you're confused as these fittings don't actually mic out to 1/4", they will measure larger but that does not correlate to their nominal size which would be the same for measuring any sort of NPT fitting.
