Okay, loyal readers, who among us knows the name of this fitting? I first encountered these fittings a very long time ago, when I was about ten or eleven years old. If you know what this kind of fitting is called, please post a comment below.

Grease fitting
Zerk fitting. Still grease them on my El Camino
Yes, that’s it! Here is the patent. I always called them Zerks. I was intrigued to read in the Wikipedia article that some people call them “Alemite fittings”.

Zerk fitting for hook-up to a standard grease gun. I saw in automobiles, perhaps they are used elsewhere.
As used by these guys to secure the loose hose while the grease gun is in storage (now being prosecuted by different counsel):

Used in plant operations all over. Many times on bearings supporting rotating shafts. Also known as “grease nipple” and not to be confused with “pipe nipple” and even “close nipple”. Common terms in the 60s, but likely out of style by now. Just a little historical perspective for y’all. 🙂
My cousin, who is in the fastener manufacturing business, says it is a “grease fitting” or “grease nipple”
Looks to me like a Zerk fitting. I remember watching my dad using a grease gun on Zerk fittings to lubricate bearings on the suspension components of our automobiles.
It is a grease fitting, commonly called a zerk fitting. This one appears to have a check valve, which they didn’t commonly have when I first became acquainted with them on farm machines in the ’50s.
Yes a Zerk. I will say that every Zerk I ever saw had this spring-loaded ball acting as a check valve. Maybe there were some that did not have a check valve, but I think every Zerk I ever saw had one.
The valve stem of bike tyre
Sorry no it is not a tyre valve stem. Thank you, though, for posting.
