What to Look for Before Buying Cordless Grease Gun?

Below I will describe the things to look for when buying a high-quality grease gun.

PSI

The importance of delivering high performance using a grease gun is immense. Generally, a grease gun with maximum PSI is suitable for removing all types of dust, dirt, and concrete components. For example, the PSI scale of a grease gun ranges from 4500 to 10,000. It would help if you chose a grease gun to overcome all the obstacles of the fittings and move forward with strength. Before you buy a grease gun, make sure it can deliver maximum PSI.

Cartridge Capacity

In general, users are reluctant to fill in the gaps when using grease guns in their industrial applications. Also, check the capacity of a grease gun and a cartridge to make sure it can deliver the cartridge for a long time. Most of the grease guns currently on the market have a capacity of 14 oz. cartridges. If you want to save a lot of greases, buy that 14 oz grease gun. Before you buy, choose a grease gun that has a lot of cartridge capacity. We would also recommend buying a grease gun that you will need to refill after a long period of continuous use.

Batteries

Do you want to use a grease gun for a long time? If your answer is a yes indicator, check that the battery is high voltage before buying a grease gun. The durability of a grease gun depends on its battery. If you use a grease gun with a high voltage battery, you will operate the gun smoothly. Conversely, if you buy a grease gun made with a low-quality battery, it may be useless after a few days of use.

Generally, use a high voltage battery grease gun to get rid of your power source problems. The most efficient of all the different types of batteries available in the market is the Ni-Cad battery, which is also a bit more expensive. We recommend buying a high-quality grease gun to handle your greasing process. On the other hand, it is best to avoid low-quality battery-powered grease guns.

Run Time

Before buying, you should choose a functional grease gun capable of delivering at least 2 to 20 cartridges after each charge. Avoid if a cartridge fails to provide adequate power for loading. In this case, you need to stop the whole greasing process while charging the grease gun. Besides, the importance of its run time in managing the greasing process over a long time using the gun is immense.

Hose

The importance of hoses in conducting greasing activities using a grease gun is immense. So when buying that Grease gun, be sure about its hose. Generally, the hose of the grease gun should be longer to reach the hard places and the stains strongly. If you have already handled the greasing process, then you must be aware of the process of applying grease in tight spaces and solid corners.

Since there is no hose option for greasing in larger projects, grease different solid areas with a working hose, that hose should be compatible enough to use with a grease gun. If you want to use it to grease different machines, use the same hose with your grease gun in the same way.

Warranty

All buyers desire to use a powerful and effective instrument like the grease gun for a long time. In general, users feel comfortable using it in the long run without any problems. Check the build components of a grease gun to be sure of its quality. Since there are currently different types of grease guns available, choose a better grease gun brand. We advise you to choose a grease gun that has a long warranty.

Final Thoughts

Use a powerful grease gun to grease anything. Choose a suitable grease gun to reach your narrow and difficult areas effectively. You can grease all kinds of things suitable for greasing with your machine with the help of a grease gun.
