You will also be impressed by the distinctive design of the Alemite 500-E grease gun, which strongly looks like a bicycle pump.

Also, the fact that it is so easy to set up that it takes only a couple of minutes to do so makes this gun appealing to many users.

However, this gun is battery powered and the battery is sold separately. In our opinion, this should have been an electric grease gun, taking into account a product of this caliber. This could have been the best electric gun in our opinion.

Best Grease Gun Buying Guide

Here are the factors to consider when shopping for the best grease gun.

The Hose Length

Cordless grease guns come with varying hose lengths, ranging from 10-inches to over 40-inches. A good gun should comprise a hose that is at least 30-inches long to be practical in certain applications where a longer hose is necessary.

Maximum Operating Pressure (PSI)

Grease guns are designed to deliver varying amounts when it comes to maximum operating pressure. A gun that can deliver a higher fluid pressure will never disappoint you in any application. The same cannot be said for one that provides a lower maximum psi.

Gun Grip

Consider the grip of the gun, making sure it is ergonomic and offers proper, comfortable as well as safe grip. Some guns provide nothing close to that. Never settle for one unless you want to have a hard time operating your gun.

Usability, Ease of Cleaning and Replacing Oil

Usability and the ease of cleaning as well as replacing grease is another important consideration when shopping for the best grease gun. A good rule is to look for a gun with a set of features that make it easy to operate and care for.

Here is where you should pay attention to things like a heavy-duty air bleeder valve to instantly eliminate air pockets, and so on.


Choose a gun with a portable design and compact dimensions that can fit in a toolbox and be carried around with ease.


Q: What is the best option between a manual, a battery-powered and an electric grease gun?

Ans: There is no best option between the three types of grease guns as each type of gun has its own list of advantages and disadvantages. For example, manual or battery-powered guns lack a cord, and hence they are more portable and easy to carry around compared to their electric counterparts with a cord. Electric guns, on the other hand, have a more powerful matter and therefore can work better than different types of grease guns.

Q: Can I use my grease gun for pumping other fluids apart from grease?

Ans: Absolutely not! These guns are built strictly for the purpose of pumping grease. Using your gun to pump other fluids will definitely destroy it.

Q: Can I replace the hose of my grease gun, which is short, with a longer one?

Ans: Yes of course! You can get a longer hose for the gun if its original hose is not long enough to help with certain applications.

Q: How should I store my gun after use?

Ans: Make sure your gun is unpressurized before storing in a clean, cool, dry area and in a horizontal position to help keep the oil from bleeding out of the grease. Make sure to cover the coupler to avoid dirt and contaminants. You can use a grease gun clamp to store your gun in an easy and organized manner.

Q: Can I use any grease with my gun?

Ans: Never! Do not use any grease other than that which is specified by the manufacturer. Otherwise, using improper grease will definitely damage your device.
