What is this thing? Ebay item

[Leakyvalve]

I was looking through ebay and saw this airbrush, but look at the accessories. I've never seen that threaded thing before.

No just browsing and it caught my eye. I had a couple of those brushes in the past and didn't particularly like them.

Don't think it is a part that belongs in the box - many times on E-bay, the brushes are "finds", withe seller not really knowing anything about them - so, if they have something they think belongs with it, they put them together. I have gotten some pretty odd stuff in old boxes.

Everything but the kitchen sink comes to mind......
I believe that is in fact an accessory to a kitchen sink. Looks like part of the hookup that comes with some of those apartment type washers to me. Just missing the T fitting.

The same is here That was funny to get.

The thing near the paint cup is not for an AB definitely.
