✅ SOLVED Hexagonal, threaded, three different metals, what is it?

[Crispin]

Pulled this little piece up today as well. The bottom has an iron circle, the body is copper, and I don't know what metal the silver color ball is. I'm sure one of you guys can ID this.

I think it may be confused......But I cant wait to see what ya have. Sometimes ya feel like a nut.

Grease gun nipple?

 

[relic nut]

maybe end to a temperature gauge that would screw in to something like a engine block

Broken zirc fitting.

 

[BosnMate]

I think it has something to do with grease, like a zirc fitting.

Roller latch for a cabinet

Googled zirc fitting. The boys were right...

 

[ARC]

First... It is ZERK with a k...
Second...
This is not grease related IMO...
Tis AIR related... like a ball valve stem part.

Zerks do not have a "ball" from my experiences.

My two cents :P

Ball ended spring plunger.

Sod Buster is right. There is one just like it on my Indian transmission. It is adjustable and fits in the shifter detent to hold transmission in proper gear but still let you shift to another gear and then hold that one in place.

 

[bradyboy]

is the ball magnetic?
First thought was a oil pan plug
The ball would collect metal shavings

Im thinking some kind of ball detent too

 

[Crispin]

The ball is not magnetic nor does it stick to a magnet. The only part that sticks to a magnet is the bottom iron disc.

 

[BIGSCOTT]

it is from a set of Victor torch guages-regulator, the ball is stainless and plugs the hole in the spring loaded diaphram as you turn the pressure
adjustment handle it puts more or less tension on the ball and raises or lowers the feed pressure of oxygen or accetalyne going to the torch

What ever you call it, alemite, greese nipple, or zerk grease fitting they are all the same. And they all have a back flow check ball valve. The ball check on the greese fitting is opposite to the ball in the item that Crispin posted:

I am going to go ahead and marked solved on this one. Not because any one idea is correct but because any one of these ideas can fit what it is. Learned a lot from the replies. Thanks everybody. I'll try to dig up something more bizarre for the next mystery item!
