## Questions & Answers

**Q: Will this take 3 oz cartridges?**
A: I don't think so. This Grease Gun is made to be individually loaded from the top (it unscrews), and there are NO springs inside the big tube to force the grease up and out. This is a very old, and very good design dating back (at least) to the 1920's and the plunger works by creating a vacuum of pulling the grease up from the tube, while pushing it into the zerc fitting. I got it use on a few old 1920 era motorcycles and found it would work on more modern design zerc fittings. To fill it, you need to unscrew the top, force the metal follower down to the bottom of the tube, and fill the grease from a tub. I only use Moly based grease and need a tongue depressor to fill the tube. There are a few explanation videos on u-tube. Bottom line - it works, it is much cheaper to operate than a 'modern cartridge type' and it will work on any size zerc. For the money you can't go wrong.

**Q: Anyone know the correct fitting to allow standard grease gun fitting to be adapted to this mini grease gun?**
A: You can, this and the other grease guns like this are all copies of the original lincoln lubrigun from the 1920-1950's. I own an original one from the 1950's and it came with a zerk adapter in addition to the needle. These came in tool kits packaged with most new tractors back in the day.

**Q: Will it work on a chainsaw?**
A: Yes it will!
.
I bought for my chainsaw and it worked so well I ordered a second. Both work great and I keep one in each case. I did have to file the tip back about .025 so the tips taper sealed the bar hole completely...........takes about 30 seconds to do with a fine metal file...

**Q: does it come with grease?**
A: No, u can use any kind of grease, I use mine 4 my air tools, wen I use to work on airplanes, I used that type of grease for the air tools, but I also have another Astro 101 for automotive grease, for those small amounts u need.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good Grease Gun & Cheap
*by M***S on August 3, 2025*

Easy to use, works perfectly, feels like it’ll hold up and it’s cheap.

### ⭐⭐⭐⭐⭐ Works well. Made better with a gasket.
*by C***8 on September 9, 2025*

So far, I'm really happy with this product. The price is competitive and it does everything that you'd expect from a small hand grease gun, which isn't a surprise given how long this design has been in production (the earliest versions date back to the 1930s and Dualco has owned the patent since the 1950s).My only gripe with the thing is the body doesn't seem to seal well against the head/pump mechanism on its own. I think this is a design feature, there's a cast slot cutting across the threads on the bump, but I can't identify the justification for its inclusion in the mold/final product. When you prime the device, you use something inserted into the bottom to force the grease into the pumping mechanism. On mine, which doesn't seem flawed from the factory, there is a little grease that escapes where the body/grease reservoir threads into the head/pump mechanism. Let me emphasize that, once fully primed and running, the tool works flawlessly. But, I still felt the need to cut a small piece of .060", oil resistant silicone gasket material to insure a positive seal. With the seal in place, the two components seam to seat together more firmly and there is no loss of function, so I'm not sure why it was omitted from the product.This is a very useful tool for bicycle and tool service/repair, and I would happily buy it again, but I think it feels better with a gasket of some kind between the body and pump. Also, Astro Tool should really have them cast their emblem or put a logo sticker on the side because there is nothing that really differentiates this from generic copies.

### ⭐⭐⭐⭐⭐ Good grease gun for a chainsaw.
*by R***K on June 20, 2025*

I have a few of these things. They work well. They not like the cartridge type grease guns tho. They work best with a thinner grease like 00. I use these to grease my chainsaw bars and such and they work well. One fill up lasts a long time. They low priced enough that I have one on the table where I clean and sharpen my chain and one in my chainsaw bag. I have a couple on the shelf in case I lose or break one.If you have a chainsaw bar that requires sprocket grease, get a bottle of 00 grease and this little grease gun. Works great. A lot cheaper than buying those disposable things.
