Dewalt power grease gun

Grease tube is of poor quality
I bought this grease gun about 2 years ago. I use it every day and it has pumped several hundred tubes of grease. The only complaint that i have about it is the grease tube is junk. Right out of the box the seals in the tube were bad, so when you go to pull the rod out to put a new tube of grease in, it squirts grease everywhere. I then bought a factory replacement tube for it. This one lasted about 2 to 3 weeks before the seals also went out on it. I am a logger by trade so I go through a lot of grease, and the gun itself works great. The tube however is very frustrating because you can not grease with the thing without getting covered in it!

Makes life a lot easier when you have dozens of farm equipment to grease every week.

Built to last
I bought my Dewalt 20v max grease gun in a pack with a charger, battery, and a blow molded carrying case in 2012 , I use it daily and it still works just as great as day 1! It is super convenient, the 4.0 ah battery last a long time, it’s light weight, durable, and includes a small led light that aids when greasing under a vehicle. I would recommend this to anyone whether you work in a shop or in the field.

I work with a drywall company and this grease gun works wonders! From greasing is cart tires to forklift harnesses to also piggy back and boom truck! It gets the job done in seconds!

Works great but had its downside
When you open a tube of Grease you would have to takeoff the metal ring at the top of the grease tube just to get it to go in and then it was a fight to latch it back down

Great product, use for regular farm greasing and includes extras I never knew I needed in typical dewalt fashion like an led light and “feet” to keep it from rolling all over the place.

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.
Does this price include teo batteries and charger

BEST ANSWER: Yes,battery and charger are included.

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.
