How Do I Choose the Best Grease Gun?

Have you ever wondered how grease was discovered? How we got to know that mechanical parts needed to be lubricated to increase efficiency? If we were to hazard a guess, we would say that a number of machines must have broken down from overheating and heat-induced expansion, prompting the search for something that would keep the mechanical parts moving without overheating and too much expansion.

It is no wonder they say experience is the best teacher. Although some may argue that experience is not necessarily the best teacher, we can all agree that we at least learn something from experience. Apart from the discovery of the need for grease, man also discovered that the mode of application can affect efficiency, hence the need for a grease gun.

Applying grease by hand is an archaic, ineffective, and often dangerous way of applying grease. Grease can be contaminated and made less effective, and there is a high chance of this happening when done by hand. It is also less precise and messier. Applying grease by hand is like cutting a tree without a chainsaw or trying to work on a car engine without a ratchet set. You may be able to do it after much stress, but why do it that way when there is an easier and more efficient way?

A grease gun is able to reach spots that a person cannot reach by hand, makes measuring the amount of grease applied easier, and lessens the risk of the wielder coming to any harm. It is simply one of many tools you’ll find useful if you have to lubricate stuff.

It’s important to always keep your machines running smoothly. You will want to find the best grease gun that does the job well for you. We have written this guide to help you do this with ease.
Price
An important factor in purchasing a grease gun is its price. After conducting thorough research, we discovered that a good grease gun can be purchased for anywhere from $10 to $300. Its price will be determined by the type, its mode of power, and its size, among other features.

Grease guns can also come in prices over or under our given price range. However, when purchasing a grease gun, we would advise against buying cheap grease guns. These tend to be poorly made and can cause harm to your machines through inadequate performance.
Features
In trying to discover the most suitable grease gun for you, it is necessary to consider the features of a grease gun. These features will vary from one grease gun to the other. By considering them in relation to what you need, you should be able to discover the best one for you. Here are some important features to consider:
  • Type
  • Maximum Pressure
  • Maximum Volume
  • Capacity
  • Size and Weight
  • Hose Length
  • Pressure Setting
  • Portability
Let us now look at these further:
Construction and Design
There are many available types of grease guns, each of which has its own unique features. Manual-lever types of grease guns require manually squeezing the trigger to perform. The needle nozzle grease gun is a subset of this, but, with a needle nozzle, you get a more precise grease application. Cordless grease guns are electrically powered but do not need to be plugged in during operation as they have batteries. Finally, pneumatic grease guns utilize air pressure to dispense the grease.

The grease within the grease gun requires a certain amount of pressure to be squeezed out of the grease gun. This pressure is usually measured in psi, and the higher a grease gun’s psi the more pressure it can produce. Grease guns can have a maximum psi of up to 15000. However, it is important to note that the maximum amount of pressure with which grease should be applied is 500psi. Any more than this and there’s a chance of damaging fittings.

It is also important to note the amount of grease that is delivered by a grease gun with each spray. Based on design, this can be measured by the amount of ounces per 100 strokes (5oz/100 strokes), or the amount of ounces per minute (5oz/min). This must be noted to accurately measure the amount of grease delivered and to avoid over or under lubricating your fittings.

A grease gun’s overall capacity is the maximum amount of grease that it can contain at any one time. This is important to note as it determines how long the grease gun can perform before it needs refilling. Some will have tasks that involve using a lot of grease at any one time and would want to avoid having to refill. For these people, a grease gun with a high capacity would be best.

Grease guns come in various shapes and sizes, and with varying weights. Before purchasing a grease gun, it is important to note how big and heavy it is. There are some whose purposes are better served by smaller, less weighty, and more mobile grease guns. Others might prefer bigger grease guns because of their implied higher capacity.
Performance and Ease of Use
A grease gun will often have a hose. This hose is the path through which the grease is delivered. A grease gun’s hose is usually made long to allow it to reach certain spots without the need to also carry the gun itself. You should consider the hose length in relation to the task you will be carrying out along with the gun’s heft.

Grease guns have an amount of pressure with which they deliver grease. However, some grease guns can have two or even three pressure settings. These pressure settings vary the amount of grease that is delivered with every spray. This is really useful because it means the user can change the amount of pressure used in relation to the fragility or distance of fittings.

For some users, it will be necessary to frequently transport the grease gun from one place to the other. To facilitate this, some grease guns have certain features that make them easier to transport. Some of these include shoulder straps and carrying cases. Some others can be disassembled to make them take up less space, making them quite portable.
