How Many Ounces of Grease Does a Mini Grease Gun Pump?

The quantity of grease dispensed by mini grease guns varies slightly because their output pressure varies as well. And the higher their pressure, the more grease they pump. With an output pressure of 3000 psi, most mini grease guns will pump about 1.5 oz or 43g of grease per 100 strokes.

Don’t aim for a gun that pumps the most grease, but seek moderation. If a gun pumps too much grease, you’ll be replacing grease cartridges often because you’ll be using too much grease. And if a gun pumps too small grease, you’ll have to grease the same spot again too soon.

Both cases are not efficient. To attain efficiency, you need a grease gun that pumps grease moderately (not too much and not too small).

How To Load or Refill 3-Oz Grease Gun?

There are three methods to load a 3-oz grease gun. You can replace its grease cartridge, you can opt for bulk refilling, and you can pump it into the barrel. However, the best and easiest method is cartridge replacement.

To do that, you’ll need to unscrew the barrel and remove it. Pull out the empty cartridge. Remove the plastic cover at the base of the new cartridge, and pop off its seal. Then, you can insert it into the barrel. Finally, screw the barrel back into place.

What To Look for in a Mini Grease Gun

When choosing a mini grease gun, here are a few features to look out for. You need to check the reviews. Choose a grease gun with a rating above 3.8 stars. Also, you need a gun that comes with a 12-inch extension hose. It will help the gun to reach tiny and difficult areas easily.

You might also consider the weight of the mini grease gun. Remember, grease guns are meant to be operated with only one hand. That can be done easily if the gun is light. So, the lighter your mini grease gun is, the better. With the three features mentioned here, you’ll never get it wrong with a mini grease gun.
