This is a good quality standard grease gun, that is built well and still economical in price. I definitely recommend it with the flexible hose.
This is a little more powerful grease gun, with an impressive 6000 PSI. It's a little more expensive, still not bad, but it is worth it if you require a powerful grease gun like this one.
This grease gun has a lever pump, instead of the standard "pistol grip" like on the others. It is the best choice if you have difficulties with your hands or just like the easier pumping of the lever.
This grease gun is operated by an air compressor. It is a quality gun and is really nice to have in the shop, although it is rather useless when you don't have an air compressor nearby.
This grease gun has become extremely popular the last few years. It operates off of a standard 20v DEWALT battery and can be used anywhere. It has plenty of power for any requirement. I definitely recommend this grease gun if you do a lot of greasing.
This is one of favorite tools I've ever purchased. It locks onto the grease fitting and the grease actually goes into the fitting and not all over the machine! I would never own a grease gun without one ever again. I recommend buying one for any grease gun you purchase, they aren't expensive and are really easy to install and use. Trust me, it saves a lot of frustration and you won't regret it.
