Grease guns require heavy equipment for regular home lubrication tasks. In short, it is useful for easy maintenance. In particular, heavy metal tools, based on bearings and bolts, have a permanent need for greases on these for smooth activation, driving, and no-soon-to-rust issues.

9 best grease guns for heavy equipment in 2023

Even in DIY projects, like sliding components together inside kids’ toys. As well, common greases, such as Lithium complex, Sodium-based, and calcium greases, are better for multipurpose. By following the gun’s manual, users can pour greases into cartridges.

Likewise, air pressures or hand pumpers, a broad variety of grease guns for heavy equipment, are available as the best aftermarket tools. 

Seems quite stressful the right picking part of a grease gun for heavy equipment. Targeting your budget, we have encountered high-quality grease guns listed below and even presented some from our experience. Go through and enjoy cornerstone FAQs and a complete buyer’s guide.

The Grease Gun Type


Obviously, the ones utilizing a battery are known as battery-fueled oil firearms. They are otherwise called cordless oil firearms or electric oil guns. These oil weapons are exact as well as have the most elevated tension. How? Since these oil guns have strong engines that can convey up to 15,000 PSI, as well as, have movable stream rates to control how much oil is apportioned per stroke. Thus, assuming that you really want accuracy as well as strain for large equipment or different weighty applications then cordless oil firearms are your ideal decision.

There are currently plenty of oil guns available, some using pneumatic energy while others use batteries and, as the name implies, these include gaseous excitation oil firearms, single handgrip oil firearms, hand siphon oil guns, automatic oil firearms, uncompromising oil weapons, and so on. We need to learn about different types.


Use air pressure to replenish oil and they are really precise because they run with how much oil is given per stroke and others have a decent amount. PSI high-pressure Air Oil firearm carries up to 6,000. Thus, if you really want accuracy and do not want so much tension, then these oil guns are ideal for this recruitment.

Hand Lever

It is a manual oil gun that works in one hand for the most part. These oil guns are not really accurate or precise but they are powerful. How high-pressure these oil firearms can give up to 10,000 PSI and basically, they are used where you really want high tension for oil fittings and the accuracy doesn’t make much of a difference. A single-hand grip oil gun is his best figure.

Unlike regular grease guns, the flexible nozzle on the gun’s top lets you rapidly fill and prevent flows outside the cartridges. Do not worry. It accepts even highly grease-loaded cartridges.

Sometimes, being bigger and weighing too much is not better at all, right? This aspect leads us to use this 555-E latest lightweight but heavy-duty jobs-compatible pistol grease gun, manufactured by Alemite. Reaching into confined areas becomes a necessary job; for instance, car washing in workshops comes in very handy.

It reinforces itself with better grease-upholding capacity, measuring 16oz. We recommend it for beginners. Like we applied at the beginning for a precise greasing experience per ounce at 30 strokes, which is flexible with an 18″ extension hose.

The process is inclusive of a high-volume mode. Instead, its lever function helps between using either high-pressure delivery or much output. However, a bleeder valve extends the motors’ lifespan by balancing pressure, and a nozzle with a coupler fits well for avoiding grease leakage.

This battery-powered is outstanding with its dispense grease category, petroleum-based. Also, adjusts 2-class flow rate settings within 10k pressures at, regarding 4-low and 6-high ounces per minute.

Factors to Consider for Grease Guns for Heavy Equipment

Pressures and Accuracy

Do you want to grease large areas within a short time? Well, you can select a huge pressure-delivering grease gun for heavy equipment. However, smaller ones will give more accuracy rather than bigger ones, for instance, household greasing. 

Instead of such a specific model, variable speed and pressure holding pistol grease gun is a breeze. Because of its modern power source, integrate toggles for changing pressures. Whether in professional lubrication tasks, pick a gun that can pinpoint exact areas by flexible nozzles and hose. Read more: Rail and Stile Router Bits Reviews


The second most critical factor in our pinpoint listing. People often think that developed countries manufactured heavy-duty grease guns may last long. As usual, all of such products may have come with stainless steel, anti-heated coating, and carbon-made sturdy materials. But this is not right. 

Well, the actual reinforced materials, like stainless steel, made guns last for longer and activate for better performance. Along with heat-resistance wearing, makes it more compatible, whether working in a warm environment.  

Safety Features

If your kids have regular movements in your tool cupboard, some heavy-equipped grease guns provide quite more or fewer safety features. One of the features is a lock mechanism. However, kids have reached your tool cabinets. But the machine will not let them activate it unless they know the unlock system. 

Some come with non-marring tips, to prevent your gun’s self-damaging. Coupler, lock, and loop are some similar safety mechanisms worth checking before shopping. 

Quick Solutions

How Does a Grease Gun Work Well?

We have listed 3 types of grease guns for heavy equipment, manual, pneumatic, or battery-powered, and modern grip guns. Each works well but in their way. Manual guns, as usual, have a plunger to take in your desired pressures. Then give a hard pop back with its spring. This type is rare at present. 

By far, pneumatic guns are comfy. While consuming electric power, enable dual or triple-speed pressure optimization. Simply push its trigger and let it lubricate. 

The last one, pistol grip guns, lets you hold its 2-pointed grips. Simply squeeze it according to your hand’s forwarded pressures. Congratulations! You have fired out grease. 

How to Load a Grease Gun for Heavy Equipment?

In general, 2 loading methods are fab. Either by an indirect method, inserting a cartridge, or grease direct filling the barrel. For the indirect one, first, unscrew the top. Then replace the empty used cartridge with a filled one. 

For direct and common barrel grease guns, first of all, hold the barrel and open the lid. Then step forward by installing the barrel end into the lubricating liquid. Now pull the plunger back; however, it remains wrapped with a coil at the gun’s back end, and you fill grease. Read more: How to Prep a Car for Painting Properly

Which Grease Type is Better for Wheel Bearings?

You can use any type of grease, depending on what you are going to lubricate. Speaking of lithium complex greases, it is good enough for trailer applications, especially for wheel bearings. To prevent hub contamination and avoid bearing, it forms an effective seal.

However, NLGI 1/NLGI 2 petroleum-based multipurpose grease is popular now. Also, the standard amount you will need in today’s modern transport sector, beyond 12-hydroxy greases. Differentiating both, you will find that modern multipurpose grease has much more water resistance and better heat covering capacity than lithium-based grease. 

Final Words

Turn to maintain any machinery by lubrication? Greases, as well, as grease guns for heavy equipment and similar services are essential parts. Limited lubrication is fine in such cases. But not enough or exceeding the limit can harm machinery. 

For having proper flexibility over your aim, it is worth checking out the above grease gun listing. Including common arising FAQs and a complete buyer’s guide for potential users.
