    Can you get a rigid pipe, 1/8" pipe to use instead of the flexible hose? The thread end that screws into the grease gun is very uncommon. Due to company rules, if we use a flexible hose, we must wear expensive gloves to prevent injury from ruptured hose. Not required with rigid line.

      The end of the hose that comes out of the freeze gun is an o-ring fitting,
      so I am not sure about replacing it with pipe. I had a hose burst awhile
      back, there is a lot of pressure. Sorry, not much help.

      To whom it may concern
      First of all I'm very satisfied with this product.
      To tell you the true I don't know the diameter of the hose fitting, but
      if you have to wear expensive gloves to prevent injury from ruptured hose, I think you also have to wear them whenever you change the cartridges because you'll be exposed to the grease.
      So I would say that with the flexible hose you can reach any hidden or of difficulty access points. In my opinion would be worth the expense.

      I think you will need some type of converter. Their chargers plug into 110V outlets in the US.

  • 20V MAX Cordless Lithium-Ion Grease Gun


    Okay I work in a diesel shop, and sense we go through a lot of grease. We have an air powered grease gun hooked into a giant grease barrel. So instead of using the normal grease cartridges we refill our guns with the giant air power gun using a grease zerk on top of our manual powered grease gun. Do these have a grease zerk on them so I can refill it using our giant air powered grease gun?

      No, a zerk is not included with this purchase

      Answered on 3/2/2016 by Ray from Atlanta


      It doesn't come with one installed but there's a port for one. Just remove the plug and screw in the zerk.
