After busting my knuckles trying to get my new grease gun nozzle loose from a zerk, I did a little research on the issue. I discovered that the nozzles are adjustable. The instructions I found say the nozzle can be screwed/unscrewed a little to tighten or loosen how tight the nozzle grabs the zerk fitting. Possibly, the end of the nozzle on your grease gun was a little too loose and was not gripping the zerk tight enough.
