As a Machine Factory OEM every bearing that comes in gets the grease using this unit
this seems to be the most economical heavy duty grease gun out there where the Lincoln was way to expensive

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.

BEST ANSWER: 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.

When charging the unit ,will this work on a 220V system.Since I am in New Zealand and the power outlet is 220V.
moe on Apr 27, 2016
BEST ANSWER: I think you will need some type of converter. Their chargers plug into 110V outlets in the US.

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?
Mike on Feb 4, 2016
BEST ANSWER: It doesn't come with one installed but there's a port for one. Just remove the plug and screw in the zerk.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
