Best Grease Gun – Buyer’s Guide 

The best grease gun enables you to keep all of your large and small gardening equipment in great working order all year round. There are many brands and styles available, and this can make it difficult to pick out the best one. However, once you pick one, you can use the best grease gun on your chainsaw, tractor, or smaller gardening tools like pruning shears or weed wackers. This short guide will help you narrow down the products to make your final choice. 

PSI

The PSI is the maximum operating pressure your grease gun puts out. Grease guns come designed to deliver varying amounts of pressure when you squeeze the handle, and this is the PSI. A gun that can put out a higher PSI will allow you to tackle a broad range of projects. One that puts out a lower PSI comes slightly more limited in the applications it can tackle, so consider how much PSI you need and what you plan to work on when you start shopping. 

Grease Gun 2 PSI
The best grease gun will prevent your machinery and tools from locking up and sustaining damage. It’s a good idea to make a routine of checking your gardening and lawn equipment before you use it for the season and using the best grease gun to lubricate it each spring.

Hose Length 

You’ll quickly find out that the best grease guns have a broad range of hose lengths. They start at a shorter 10-inches long and go up to over 40-inches long. Ideally, your gun will have a hose that is at least 30-inches long because this will give you enough room to maneuver without being too long to store in your shed. It’ll allow you to get into your tractor or lawn mower or work on smaller machinery without getting in the way. 

Usability 

You’ll most likely be using this best grease gun a lot to keep all of your equipment ready to use and in good condition, so there should be a high usability factor. It should be easy to clean, break down, and open to replace the grease when you run out. Look for a gun that comes with a set of features that improve the usability like multiple grease loading options and heavy-duty air bleeder valves to help you get the pump primed as quickly as possible. 

Grip

Take a look at each gun’s grip when you start shopping. It should be ergonomic, and it should offer you a comfortable, proper, and safe grip. It should contour to your hand, and some come with anti-slip sleeves or properties that make it safer to use. It won’t slip out of your hand when you’re using it to lube your weed wacker or pruners. The grip should extend to the lever too, and it should be easy to hold the grease gun while you press the lever. 

Grease Gun 3 End
A grease gun gives you superior control when compared to grease or oil cans. They allow you to get closer to your parts or machinery without worrying about anything spilling, leaking out, or making a mess. 

Portability 

As a general rule, the best grease guns are highly portable because they’re small and compact. However, longer hoses make it slightly more difficult to pack these guns up into your toolbox or bag and carry with you. Double-check all of the sizes before you buy and make sure you can carry it around. You also want to make sure you have space to store it where it’s ready to get when you need it. 

Bottom Line

The best grease gun can be a very handy tool to have in your arsenal. My reviews of the 10 best grease guns give you examples of high-quality products you can consider. The reviews allow you to compare them side-by-side, and the short buyer’s guide highlights the important pieces you can consider when you try to narrow down your choices and make the best pick based on your needs and wants.
