What Are Grease Guns?

Grease guns, as the name implies, are tools used for the efficient transfer of grease onto fittings of various machines from automobiles to farm and large factory equipment. They are considered to be staple garage or workshop tools used for lubrication and are owned by a variety of people, from simple homeowners to industrial mechanics and farmers.

The tool comes in various shapes and sizes depending on which type you get, but every regular grease gun has a plunger at the bottom which pushes the grease up and a lever which pumps it out of the application nozzle onto grease zerks.

One of the advantages of using grease guns is their efficiency in maintaining the saturation of grease used when applied onto a machine fitting. More importantly, the tool also utilizes the amount of grease used as most models come with components which control its flow when applied. Having a grease gun also helps in ensuring the longevity of other expensive tools or machines.

However, you should take care when using this tool, especially grease guns with needle-point fittings. Most pneumatic (air-powered) grease guns inject lubricant at a rate ranging from 246.6 psi to 5801.5 psi. At this pressure, it is possible that when the needle-point slips and accidentally punctures a finger grease might be injected up until the palm or the wrist. This may lead to an infection and maybe even gangrene if not immediately treated.

Types of Grease Guns

The tool may be powered in three ways: by hand, air or electricity. Generally, there are four types of grease guns. First, is the manual lever grease gun which is the most common type and can churn out about 1.28 grams of grease per pump. It is powered by hand and does not require either batteries or electricity making it cheaper than other types of grease guns. The second type is a variation of the manual lever. It is called the manual pistol grip grease pump. Its advantage is that it may be operated using only one hand. However, it pumps less grease at only 0.28 grams.

Another type is the pneumatic grease gun which uses compressed air directed into the gun through a hose. The pneumatic grease gun allows you to prevent wastage by providing only the accurate amount of required grease per pump. These are more expensive than the manual types and also a fair bit heavier. The advantage of the pneumatic gun compared to the electric gun is that the pneumatic type is more portable and reliable as it does not use electricity, making work possible even during power outages.

Electric grease guns are cheaper than their pneumatic counterparts. They may be used to lubricate both light and heavy equipment and produces less noise than the pneumatic grease gun.  Aside from its quiet features, its light weight also makes it ideal for household purposes.

The last type is the battery-powered grease gun, another popular variation of the tool. It works similarly with the pneumatic type and comes as low-voltage and cordless, which is a great advantage for mobility.

Being high-powered and not to mention relatively more expensive, electric, battery-operated and some air-powered grease guns are only recommendable to those out there who are looking to use these tools for commercial and industrial purposes. Mechanics in the automotive, manufacturing and agriculture businesses would find these types of grease guns to be worth the investment given their need for regular use of grease guns to maintain heavy and expensive machinery.

Considering Amazon sales and opinion of actual people who have bought and used the grease guns, we found that the brands Lincoln, DeWalt, Astro, and Milwaukee are among the most trusted and purchased by consumers.

Meanwhile, DeWalt Power Tools started out as a producer of electronic woodworking tools in the 1920s. At present, they are one of the leading manufacturers of power tools in the USA.  Both brands produce and sell the different type of grease guns discussed previously above.

Astro Tools is a family-owned company boasting quality but affordable tools used for mostly garage work and household toolboxes. On the other hand, Milwaukee, an international company, produces a wide range of products from simple hand tools to power tools and supplies these worldwide as well.
