Top 7 Best Grease Gun reviews

When the bearings fail, most car owners blame it on the quality of grease, but the experienced drivers can assert that the way you carry out lubrication can also cause breakage of your vehicle’s moving parts. A grease gun is a tool used to supply lubrication to different car parts (bearings, valves, transmission parts, etc.), which is used by both car owners and professional mechanics. The best grease gun is one of the most convenient, quick, and precise kinds of equipment used to eliminate dry friction.

Actually, all grease guns have approximately the same working principle: the pressure is pumped in the cylinder due to the reciprocating action and the lubricant is squeezed out through the rod by a piston. When high pressure is reached on the nozzle, a lubricant enters the hose via an open valve.

So, if you need a tool that is able to reach car parts that are subjected to significant loads and prone to quick wear, you definitely should think about buying a grease gun. However, the choice of the right tool can be confusing because the modern market offers a great variety of different types and models of the grease guns.

Buyer’s Guide

Instructions on How to Load a Grease Gun

Before you begin loading a grease gun, check if the grease you are going to use fits your tool. In case it is too thick or too liquid, your grease gun can break or simply won’t work. You also shouldn’t blend two types of grease together as they never mix well so you will only waste the grease and break your tool.

The grease gun loading isn’t a hard process even if you have never done this before. However, it’s very important to strictly follow the instructions if you want the process to be quick and trouble-free. Follow our step-by-step manual to load your grease gun.

  1. Detach the cartridge. The grease gun has a two-part construction: the first part includes a cartridge with grease, and the second one includes barrel and cap with a nozzle. Detach the cartridge by unscrewing the cap. Do it clockwise while rotating the barrel in the opposite direction. You may need to put some physical strength into it.
  2. Remove the metal rod. It’s used to exert pressure on the cartridge, forcing the lubricant to come out. The metal rod can be found in the grease gun center, where the cartridge is located. Pull it until it comes out completely. Once the rod is extended, it should be firmly fixed.
  3. Remove the cartridge. Commonly, the construction of most grease guns is designed in such a way that in order to get the cartridge, the rod must be moved to the side. You will no longer need the removed cartridge, so you can safely discard it.
  4. Prepare the new cartridge for installation. Remove the grease residue left from the old cartridge by wiping the barrel with a dry cloth or rag. Remove the cap from the new cartridge. Note that if the cartridge has been stored upside down, the grease will accumulate on the right side. If it has been stored in the standard position, shake it several times before installation in order to make the grease settle in the right direction.
  5. Install a new cartridge. That part of the cartridge that had a cap on it must be located in the front. The end of the cartridge with the seal must fully coincide with the end of the barrel.
  6. Assemble the grease gun back. Unblock the rod and press it to the barrel. At the same time, you need to press the handle of the nozzle to get rid of air in the barrel. Stop pressing immediately after the grease appears from the nozzle. Attach the barrel and the head by rotating them in the opposite directions. Remember not to screw too tight, it will cause a pressure drop in the grease gun, making it impossible to use.

Make sure that the grease is delivered by pumping the handle.

Guide on How to Use a Grease Gun

When using a grease gun, you shouldn’t forget about safety measures:

  1. Don’t apply lubricants to a running vehicle.
  2. You should always maintain proper footing and balance to make it easier to control your grease gun in unexpected situations.
  3. It’s better not to let the lubricant get on your skin, especially if you have any wounds because all lubricants have a certain level of toxicity. Wash your hands after you finish working with a grease gun.
  4. Check the hose before each use. If it’s damaged or worn out, it may rupture causing fingers or hands injury.
  5. The pneumatic and electric grease guns can create extreme pressure that is insensible to the user. Therefore, be careful when working with this kind of tools.
  6. The electric grease guns require following special safety measures: turn the gun off before inserting the battery, keep the tool away from water and any metal objects.
  7. Make sure to read the instructions provided by the manufacturer of the grease gun you own.

To start using the tool, place the grease gun coupler directly on the area to be greased and press the handle several times at that moment when you need the grease to begin flowing. The harder you push the handle, the more powerful jet of lubricant fluid you will get. Note that the hand-powered grease guns will make you put some effort, but the electric tools and tools that use an air compressor provide an increased working pressure and feed rate, so be careful.

Don’t neglect cleaning the grease gun after each use. Having dried grease inside, it will start causing troubles and become unusable over time (or at least difficult to use).

Pros of Using a Grease Gun

Of course, the quality of lubricant is important, but the improper tool for lubrication can also cause some issues. That is why you should be attentive when choosing the one. There are a bunch of reasons why the grease guns are considered to be one of the most effective and reliable tools for lubrication:

  • Accuracy of application. Thanks to its long and flexible tube, the grease gun is especially convenient to accurately lubricate hard-to-reach areas. Plus, some models allow changing different kinds of nozzles to carry out various types of lubrication.
  • Convenience. If you don’t like bulky garage tools, you can get a grease gun with 3 oz cylinder capacity which is perfectly small for one-handed operation.
  • Grease waste prevention. The grease guns supplied with the flow meter allow controlling the amount of grease being used. This helps avoid damage to the bearings due to excessive or insufficient lubrication. So, thanks to the ability to measure the adequate amount of lubricant, it prevents grease spills and wastes.
  • Cost-efficiency. In relation to preventing spills and wastes, the grease gun will help you save some money on buying grease, oils, and lubes.
  • Longevity. Based on actual users, the grease guns have durable built and structure that is enough to last for more than a decade.
  • Reliable lubrication. Since the grease gun delivers lubricant under pressure, all car parts will be lubricated as well as possible.
