Grease Zerks

I have a couple of zerks that are packed and won't accept grease anymore. What is the replacement size/type? Thanks. David.

Most of the zerks are 1/8”NPT threaded. It depends on the location on the machine if they are straight, 90 degree or 45 degree. Screw the old ones out and go to any auto parts or farm supply store and get new ones. I always buy extra to keep on hand.
If after you put in new ones and it still doesn't take grease you'll have pull the pin and clean the hardened grease out of the holes.
