Help me identify this adapter please

[Huncowboy]

Sorry! This is not PCP related but this is the best place I know of to ask anything about compressors. I have this old portable tire compressor that still works but I cannot figure out what standard this adapter is and the female part is gone. Any ideas? It is quite large. Larger than the typical ones. Thank you!

Ring Lock. Probably 1/2" or 3/4" hose size.

That's a 1/2" Asian style hi-flo connector. Not common in the US, but I have run across them.

Your best bet is to ditch them and go with US standard style automotive or industrial connectors to avoid headaches, IMO. SO MANY of these to choose from. But the style does matter. A lot.

Looks like a Japanese QD style fitting....
