Return pump new piece needed

[Arabianmagic]

Okay so picture one, the black piece connects to picture two, the pump....... I messed up with the union and need to find a replacement for picture one .. but it moves and I don't know what it's called....
.does anyone know where I could get a replacement piece?

I did the same on one of my Simplicity pumps. Had a heck of a time trying to find a replacement. Ended up having to contact the manufacturer to get one sent to me. Maybe find a local reefer that might have a spare ring?

Looks like a Jebao unit. Not many parts around
Best pet is to buy a used unit (ebay, amazon, Craigslist or R2R)
