The Complete Buying Guide to Follow for Best Electric Grease Gun

Choosing an electric grease gun is tricky where you are getting a vast amount of options to choose from. In that case, you’ll need proper guidance so that you can choose the best electric grease gun for yourself.

In this article, I’ll point out some topics as the buying guide which will help you to enhance your knowledge before selecting the best electric grease gun –

Features You Need

It is the most important part you need to consider before buying an electric grease gun. Some grease guns will provide you 6000 PSI or max pressure and some with 10000 PSI, you need to choose according to your work style.

A flow rate of 5 oz./min is an ideal example of your tool. But if you are working on bigger projects then you should be considering a higher flow rate. The extended run-time feature is always appreciable.

If you are not comfortable using heavy products, then you should consider their portability. It will enhance your productivity.

Range of Application

The first thing you need to consider is why and where you’ll need the grease gun. If you are experienced lubricating the ball joint of a tractor then you’ll get different experiences greasing a lawnmower.

If you are doing some DIY projects or small lubricating jobs, then you should go for portable options like cordless grease guns. Small lubricating projects will not need too much operating pressure and you should be okay with a medium amount of flow rate. A lightweight feature should include in your grease gun so that you can move if comfortably.

For larger greasing projects and professional use, you should get grease guns with greater operating pressure such as 10000 PSI, more flow rate and grease capacity, long flexible hose, higher voltage, etc. Grease guns with these features might be a less portable option for you but it will do the work done. You should never allow yourself to go for a cheaper option, it will just create a working mess, find the best quality for you.

Loading & Delivery Methods

You should always consider the grease gun loading method because a different person has different preferences. Loading is a primary knowledge before using a grease gun and it should be in the way of your comfort.

You can load your electric grease gun by cartridge or by suction, some of the grease guns have both ways of loading.

The cartridge loading method is the best option for your grease gun because it is more convenient and clean. Although this method is expensive than the suction method. The suction loading method is messier and cheaper than the cartridge loading method.

Both methods work well for loading, but consider the differences I’ve said before buying your grease gun.

The reason why you need considers the delivery method is that you should be able to control the amount of grease you want to release from the gun. A different amount of grease is needed for a different project. Hand-operated grease gun’s delivery method lets you have more control over grease flow. On the other hand, the pneumatic grease gun’s delivery method is to push grease through compressed air and ideal for larger commercial projects.

Included Accessories

It’s not wise to buy just the grease gun alone, before buying the product you should consider the accessories it offers.

Having a durable case included with your electric grease gun is great because it ensures better protection. If you are buying a battery-powered model then having batteries included with the product will save your money.

If your product is offering spare parts, that is good too. Always check the quality of the tools before buying.

Buying from renowned brands like DEWALT, Lincoln, Milwaukee, etc. will ensure you better quality products because these brands make the best electric grease gun.
