simalube automatic lubricator refill cartridges, includes dry cells

simalube automatic lubricators can be refilled up to 3 times before they need to be disposed of.  Replacing the gas cartridge is done by simply removing the cover and unscrewing the old cartridge from the lubricator.  The new cartridge is screwed into the lubricator and after filling with new grease or oil, the lubricator is ready for another round of lubrication.

Each lubricator size has it's own size refill cartridge and they are not interchangeable.
