Are you the guy who posted here before of your Honeywell hydronic zone valve being sticky?
If so, I worked on one after we exchanged posts, and here"s what I found... a stainless steel stem, about 1/4" OD.
It has 3 grooves and 3 tiny "O" rings.
If that is what you have, penetrating oil isn"t going to work "cuz the 3 "O" rings pretty much fill the bore and oil isn"t going to get in there.

This one worked, didn"t stick, but was apparently weak.
