Buying A grease gun – Things to consider

A grease gun is a must-have for all projects that require lubrication. Before you purchase your grease gun, it is important to spend some time to understand the different types of grease guns available in the market. This guide will help you understand the different types of options available.

1. Type of Grease Gun

There are mainly 5 different types of grease guns in the market: Hand pump lever gun, Manual lever grease gun, manual pistol grip grease gun, pneumatic grease gun, and battery powered grease gun.

Hand Pump Lever Gun
A hand pump lever gun comes with a lever on the top of the gun. When the lever is pumped, it creates pressure inside the gun which pumps the grease out. This type of lever gun can be slightly difficult to operate as it requires a lot of effort.
Manual Lever Grease Gun

A lever grease gun comes with a manual lever. It is the most common type of manual pump grease gun that is available in the market. The lever grease gun uses a manual lever to pump the grease out of the gun by hand. When the lever is pulled, a pressure is generated that pushes grease out of the pump. In most models, you can vary the amount of grease that comes out of the nozzle by varying the length of the lever stroke. Both hands are needed for using this type of lever pump because the nozzle of this gun must be placed and fastened at the right place before it can be used.

Manual Pistol grip Grease Gun
A pistol grip grease gun allows you to apply grease by using a single hand instead of engaging both your hands. These guns come with a pistol like handle and they can be used for lubricating places that are confined or difficult to reach. Manual pistol grip grease guns can be used in both domestic and commercial applications.
Pneumatic Grease Gun

Pneumatic grease pumps apply grease by making use of compressed air. They’re more reliable than manual pumps for lubrication and are mostly used in commercial projects. Pneumatic grease guns are powerful because they’re attached to air compressors that generate the pressure to release the grease form the gun.

Battery Powered Grease Gun
Battery Powered Grease guns come in handy when you want to work in places where a cordless greasing device is required. It is easier to work with battery powered grease guns because there are no tangling cords of the gun getting in your way. Moreover, Battery powered grease guns also make the job easier as the grease is released due to the energy provided by the battery. The use of manual power with battery powered grease guns is minimal.

2. Pressure

Pressure is another important consideration for buying grease guns. Grease guns operating at a pressure of 5000 PSI work great for domestic applications such as lubricating the lawn mower or washing machines. However, if you want to use the grease gun in commercial settings then it is recommended to have a pressure of at least 10,000 PSI to ensure optimal performance in getting the job done. The pressure of a gun directly correlates to its power.

3. Cartridge capacity

The cartridge capacity of your grease gun will vary from one project to another. If you’re looking for a grease gun for small DIY projects or domestic projects such as greasing your squeaking gate or lawn mower than a small grease gun having a cartridge capacity of around three ounces will get the job done. However, if you want to use the grease gun in a commercial setting such as farms or factories go for a gun that has a cartridge capacity of at least 14 ounces. A gun with a cartridge capacity of 14 ounces will make it much easier for you to lubricate large vehicles such as trucks and tractors, and other large equipment in your space.

4. Output per Stroke

Output per stroke of the grease gun dictates how much grease is applied each time the grease gun is used. The output per stroke varies from one model to another. It is important to know the output per stroke of a grease gun so you can know how much grease you are applying with each stroke. The output per stroke of grease guns can vary from 1 gram of stroke to 3 grams of strokes of grease.

5. Warranty

Go with a brand that offers a good warranty with minimal conditions. A product’s warranty is indicative of the trust a brand places in their product. Most good brands provide at least a year’s limited warranty of their grease guns.

6. Features

A good grease gun doesn’t have to come with complicated features. For domestic use, a budget-friendly, durable, and user-friendly manual grease gun with a 3-ounce cartridge capacity and a comfortable grip works great.
For experts in the commercial industry, a grease gun with higher-end features is recommended such as a flexible hose, Bright Led Lights, variable speed trigger, continuous flow and more. Automatic or air-pressure grease guns are more suitable for commercial situations.
