"Alemites?" Interesting...is that a term for zerk fittings?
Alemite was (is) a brand of grease fittings from way back. The term "zerk fittings" is named for the inventor Otto Zerk. They differ slightly.
Here's an interesting read, containing some info I was not even aware of till now. The interesting part is that modern grease fittings should not be called zerks, as they are a different pattern, with zerks being tapered, not ball shaped.
