Additionally, the included carrying case is made from plastic and not as durable as those made from steel and metal alloys.

Despite its light form factor, this is not a mini grease gun, as it still uses the large 14-ounce cartridges. Also, we found the 7,000 psi motor to be adequate for most DIY jobs, but it is slightly less powerful than our top pick. All in all, this is one of the best grease guns on the market that you can use for your next DIY project.

This grease gun also features an automatic upgraded exhaust valve that bleeds air automatically so no need for manual exhaustion as you are loading grease.
Though the working pressure goes up to 7,000 psi, ably handling most DIY projects, we did find that the power on offer was slightly lower than what was featured with our top picks.

We also made sure that each of the above products were light enough for one-handed operation, within some items excelling with this more than others, and that they featured ergonomically designed handles, increasing stability during use. We also made sure to populate the above list with a series of multi-featured standard-sized designs that function with 14-ounce grease tubes, and smaller mini grease gun designs that use 3-ounce tubes, in addition to several products that allow for the use of bulk grease.
As far as accessories, we made sure that everything you need to get going is shipped in the box, including hoses, nozzles and couplers, among other useful objects.

Best Grease Gun Buyer’s Guide
The Most Important Features to Consider
- Motor Types and Pressure
You may want to choose a product with a powerful motor and a high volume pump, such as what is found with our top pick. Not all grease guns use traditional motors to achieve the desired results. Some models are pneumatic or air-powered, which apply grease via a trigger powered by compressed air. Other units offer a more traditional manual design, which emits grease by pushing and pulling on a hand pump. Generally speaking, grease guns with an actual motor, such as our top pick, are great for industrial-grade uses but may be overkill for simple DIY jobs. - One-handed Design
Most, though not all, grease guns are manufactured to allow one-handed use. Lever-handle grease guns on the other hand require two hands for precision. Look for products with light form factors and those with ergonomically designed rubber grips and handles, reducing the chances of accidentally dropping it. - Standard and Mini
There are two sizes of grease guns available for purchase. Those that use standard 14-ounce canisters of grease and much smaller products that function with three-ounce tubes of grease. Each has its benefits, with the mini grease gun designs typically coming in at cheaper price points. - Accessories
Modern grease guns come with all manner of useful accessories, including lengthy and flexible hoses, to reach out of the way spots, and a number of couplers, nozzles and related pieces of equipment. Some products also arrive pre-lubricated, so you can begin using them immediately after opening.
