A Question About Grease Zerk Caps

[camaron32]

I know that grease zerks can vary where they screw or press in, but are the rounded ends a standard size? I want to put caps on the zeros for my Ram 1500 and my John Deere riding mower. Any advice would be helpful. Thanks.

The zerk fitting end where you put the grease gun coupler are all the same size no matter if it is threaded or pushed in.

Wouldn't multiple guns for different size zerks be a royal mess - no pun intended. Count that as one thing they standardized for our benefit.

There are a few different styles, but most automotive uses are the same. I have more than a few of the button head around, and have used the pin style.

I like the caps with a retaining ring.
