What's it #2 - I found this in my tool box

[Snattlerake]

I found this in my tool box waaaay in the back while I was cleaning the box and tools.

It is knurled aluminum.

I'm assuming it is air operated because it has two check balls and one spring. The ends are different size holes and are threaded.

My guess, it is something for a bike tube?

hmmm, all i know is with the ATF these days i wouldn't let them see it.

Looks like a fitting that should have a grease zerk in one end and screws onto something. Since it has two ball check valves, I'm thinking maybe it is two different fittings screwed together so the inner parts don't fall out. Like it is nothing would pass through it.

Is it to fill a bike tire with a C02 cartridge?

Grease gun fitting.

Would it balance pressure somehow?

Did a good job with the knurling. As for what it is, no idea.

Grease gun fitting.

Actually I think that’s what it is. It’s one of those pump up grease guns.

It doesn't fit a zerk. The openings are threaded.
