I bought this air hose reel and it says it is distributed by Costco UK.. So here begins the problem I guess, A short 3 ft hose is supplied for connection to the reel, the connection at the reel is male, has a tapered seat Inverted, threads outside, crude art below

The 3 ft hose has a swivel threaded body outside and the reverse of the seat inside.
I thought it was JIC, but usually not inverted like this. I can't figure out what this might be except possibly something called NPSM that outside thread does not seal but the cone seat seals it... I am trying to adapt this to NPT. I looked through mcmaster heavily and cannot I.D. it or found any adapters like this.
Thanks
