Its power and performance separates it from the rest of the pack. Exceptional battery life and very durable build.
It's the most costly model on our shortlist, but it has a lot to offer for the price.
Air operated and fully automatic performance provides precise flow of grease. Has a flexible yet rugged 30-inch hose.
Not as powerful as the Dewalt. Valves have a tendency to stick on some units, but it doesn't seem to be a persistent issue.

At 12 inches, the flexible hose is slightly shorter than similar models.
Built to last with a heavy gauge steel barrel. Boasts chrome plating on the handle to protect against rust.

Do you own a grease gun? If so, performing your own maintenance on that lawn mower may be easier than you think. The main purpose of a grease gun is to help you keep your vehicles and equipment running smoothly. Using a grease gun, you can deliver grease to any mechanical area where moving parts need to operate smoothly, without too much friction and heat.
Perhaps you’re experienced at making repairs and ready to upgrade to an automatic grease gun. Or perhaps you’re looking to buy your first manual grease gun in an effort to lubricate your equipment. In either case, BestReviews is here to help.
Read the shopping guide below to learn vital information about buying a grease gun. Then, slide on up to the top of this page to view our favorite grease guns – the ones we think would be the best use of your hard-earned money.
There are two basic grease gun types: manual pump grease guns and automatic pump grease guns.
A manual pump grease releases grease when you squeeze it with your hand. It has a spring-loaded piston pump that, in most cases, pushes the grease from a pre-loaded cartridge through the nozzle.
The manual pump sometimes has an extension hose to help you get into smaller spaces. Some manual pump grease guns can be refilled from bulk grease rather than cartridges.
Most home use and automotive use needs can be addressed by a manual pump grease gun.
Under the automatic pump grease gun umbrella, you’ll find both electric and pneumatic grease guns. These guns work by pulling a finger trigger. They’re quicker for applications in which you have a lot of points to grease.
An automatic pump grease gun is ideal for industrial or agricultural equipment.
The size of grease gun you need depends on what you are trying to grease. Smaller equipment, such as a lawn mower or tiller, will require very little grease compared to larger vehicles such as tractors, trailers, and trucks.
Grease guns are sized according to what cartridge size you will need to buy for the gun. There are two standard sizes which cover most uses: grease guns with three-ounce cartridges and grease guns with 14-ounce cartridges.
Smaller grease guns have three-ounce cartridges. Designed to apply small amounts of grease at a time, these guns provide ample lubrication for lawn and boating equipment. Because they’re so small, you can easily store a three-ounce grease gun in a tool box or the glove compartment of your car.
It is not recommended to mix different types or grades of grease. If you put one type of grease over another type of grease, it could degrade the grease that is already in the joint and damage the joint.
Grease guns generally come with some kind of extension that attaches to the body of the grease gun. The extension is either a pipe or a hose.
A grease gun will be easier to use if you have a longer extension hose or extension pipe, and that’s typically what you’ll get with a grease gun. However, if you have a tractor trailer, a farm tractor, or an RV fifth wheel, you may need an extended hose for tight places that are hard to reach.
Automatic grease guns have much longer extensions than their manual counterparts. They will give you a couple of feet extension with the hose.
It takes a little force at times to hold your grease gun on the grease zerk and apply the grease. Some grease guns come with hand grip springs to aid in holding it on to the grease zerk.
Grease guns come with different types of pump action. Check the packaging to determine how much grease is delivered with each pump.
Long-handle manual grease guns can be more difficult to operate, requiring more arm action. However, they do allow you to push more grease per squirt.
Hand grip grease guns are easier to operate, but they tend to deliver less grease per pump. Your hand may get tired more quickly using a hand grip grease gun.
When you operate an automatic grease gun, you can hear each pump cycle. You can count the number of cycles to determine how much grease you are delivering into the joint.
The range of prices on grease guns is wide because there are so many types from which to choose. Here are some of the features you will find at different price points.
If you decide to purchase a battery-powered grease gun, consider a package deal that comes with a charger and a carrying case. For some people, this is a real money-saver.
Evaluate your storage options before you buy a new grease gun. Cheaper grease guns have a tendency to leak, which can make storage difficult.
The built-in LED lights on some automatic grease guns are very handy for helping locate your grease zerk in tight spots.
Q. How do you know where you need to grease?
A. The piece of equipment you own should have grease points explained in the maintenance manual. You may not need to grease all moving parts, as some come pre-greased and sealed.
Q. What is a grease zerk?
A. A grease zerk is a fitting that works like a valve. It screws on to the end of a joint on your vehicle or piece of equipment and allows you to hook your gun to the joint and pump grease into the right place. There is a ball in the middle of it that allows the grease to go in, but it does not allow the grease to come out through the same fitting.
Q. How do you know when you’ve applied the right about of grease with your grease gun?
A. There are two ways to know, and it depends on the joint you are greasing. Some maintenance manuals specify how many pumps you need to apply. If you do not have that information handy, you can also visually see if you have put enough grease into the joint, because the grease will start to come out of the joint when it is full.
