  1. Any of a class of types of grease nipples, or an instance thereof; (usually, in current usage) any grease nipple.
    — The moral is, if you don't keep grease in those zerks, you're going to be replacing some expensive parts. To grease through a zerk, you simply push the business end of a grease gun onto the zerk—it will pop right on with a little pressure—and work the handle until a bit of grease can be seen oozing out of the joint you are lubricating.
