Best Grease Gun Reviewed: BraveX Mini Lubricant Gun

BraveX Mini Lubricant Gun Description: BraveX Mini Lubricant Gun is a small lubricating oil gun that works on all types of automotive fluids. It comes with a pump mechanism which allows it to spray out the fluid in large amounts. You can use it to clean your engine block, transmission, differential or any other part where there are oils or greases present.

Pros:

It’s compact size makes it easy to carry around.

You don’t need to worry about spilling the contents of the bottle since it has a cap.

The pump mechanism allows you to spray out the amount needed without having to wait for it to cool down before spraying again.

Cons:

There is no way to control how much you want to spray out. If you accidentally spill some, then it will just keep coming until you stop spraying. This could cause damage if not handled properly.

The pump mechanism does have a tendency to get clogged up easily. If this happens, then the whole thing might break down completely and you won’t be able to use it anymore.

It also comes with a stainless steel nozzle which is designed to have nozzles attached to it thanks to its special threading.

Pros:

This gun can be used to pump out various types of materials including water resistant grease, water soluble grease, petroleum jelly and more. You can also use the stainless steel nozzle that comes with it to pump out regular cutting oil and other fluids as well.

The maximum pressure it can handle is 150 pounds per square inch which means it can pump out most types of materials.

The adjustable nozzle allows you to control how much comes out of the canister. You can choose between a fine mist or a heavy stream.

You can also detach the nozzle and store separately which helps to prevent clogging.

Cons:

It can get messy if you don’t detach the nozzle and store separately. The full pressure of the gun comes out when attached so you have to squeeze really hard when using this feature.

The metal canisters can be quite heavy and is not likely something you would want to carry around if you had to do it for a long period of time.

The fact that it has a wide temperature and pressure range also makes it more versatile when it comes to the types of materials you can use with it.

Cons:

It only holds 3.5 ounces of grease which means you might have to refill more often than the other units on our list.

The temperature range of -30 to 250 degrees Fahrenheit may be a little limiting if you need something that can work in a wider range.

Things To Consider Before Buying

Material Of Construction

The materials that are used to make the grease gun itself matter a lot. If you buy a cheap model, then it’s going to break quicker and you’ll have to buy another one. So you need to determine what features are the most important to you and buy a unit that has those attributes, while avoiding the less important ones that have a tendency to break.

For example, you really don’t need an aluminum grease gun if you’re just going to be doing normal routine automotive maintenance. These guns are great if you’re going to be working on huge ships or in a professional setting, but they aren’t necessary if you’re just doing small jobs on the side.

Pressure Capacity

The higher the pressure capacity is, the less often you’ll need to refill. Again, if you’re just a weekend warrior who’s working on your personal vehicles, you probably don’t need a gun that can reach up to 1,000 pounds per square inch.

Most of the guns on our list have pressure capacities that range from 20 to 1,000 PSI. You can get by with a lower capacity if you’re just doing general maintenance, but if you’re working on bigger jobs and expect the gun to take a beating, then it might be best to buy one that has a higher PSI rating.

Nozzle Style

Nozzles are very important because they control the flow and the pattern of your grease. If you’re doing routine maintenance, then you don’t need a gun with a ton of fancy nozzles. The straight and spiral nozzles are more than enough for normal use.

However, if you start doing jobs that require more grease or in an area where the space is very restrictive, then it might be a good idea to buy a gun that comes with some sort of pistol grip or multi-nozzle system.

Size And Weight

If you’re just using your grease gun for personal use, then weight probably isn’t that big of a deal. However, if you’re going to be working on your knees or overhead then you’ll want to make sure the unit is light enough for you not to get fatigued.

Most of the models on our list weigh around six pounds which some people might find a little on the heavy side. If weight is a concern for you, then it might be a good idea to buy a unit that has an aluminum body instead of steel.

Types Of Grease

Most grease guns use either a .50 or a .62 cartridge. The .50 cartridge is shorter and fatter while the .62 cartridge is longer and skinnier.

The main difference between the two is that the .50 cartridge holds less grease meaning you’ll have to refill it more often. This is why most professional mechanics opt for the .62 cartridge since they’re constantly pumping grease for hours on end and don’t want to have to stop in the middle of a project to refill.

The cartridges also come in various thicknesses depending on the temperature range that you’ll be working in. The thicker the grease, the better it insulates from high temperatures. Most people buy the thickest grease that is closest to their work environment, so if you’re using your gun for home use, then you probably don’t need to worry about this since homes aren’t nearly as harsh on grease guns as car shops can be.

Grease guns are not complicated machines, so there isn’t a whole lot that can really go wrong with them. The most common issue that people run into is the o-rings getting worn out. O-rings are what allow the grease to get pushed out, so if they’re worn then you might have troubles pumping it. In addition to this, the trigger and trigger mechanism also take a lot of abuse, so always be sure to clean them after you’re done using the gun.

Safety Tips

Grease guns can be a little on the dangerous side if you don’t handle them properly. Here are some general safety tips to remember:

Always be sure to wear eye protection. If you’re doing a job that has the potential for flying metal or debris, then it’s best to also wear ear protection and a dust mask as well.

Be careful when working around electrical equipment, especially anything that powers the car such as the engine or transmission. The last thing you want is grease mixing in with the oil or getting on the battery terminal.

When you’re pumping grease, always hold the gun at a downward angle towards the part that needs grease. This will prevent any unwanted grease from splattering out of the gun and onto your clothes or skin.

Grease is designed to be slippery, so when you’re done working, always wipe off any excess grease on your clothes or skin before you handle any metal objects or go anywhere near an appliance. You wouldn’t want to get any grease on a $5 bill, so don’t go putting it on the door of your $5,000 car.

After you’re done using the grease gun for the day, be sure to clean it thoroughly with some detergent and re-lubricate all the parts. This will ensure that it lasts a long time without any problems.

Always remember that when working with grease guns, safety should always be your number one priority. If you feel unsafe performing a task, then there’s probably a good reason why.

Always remember to follow your owner’s manual to the letter. Every model is different, so you don’t want to do something that could possibly damage the gun and render it useless for future use.

Grease guns are great tools to have around the house. When used properly, they can help you do your job quickly and safely. Just remember that you’re pumping powerful grease through the thick cartridge at a high velocity, so if you do something dumb like point it at your hand and pull the trigger, then you’re going to be in for a world of hurt.

Hope this guide has been helpful. Keep these tips in mind when working with your grease gun for best results.
