Milwaukee 49-16-2648 M18 Right Angle Coupler Grease Gun

By far the best fitting adapter I have ever used. You can find cheap ones but this one out performs them. Hands down.

:)

Adapter went on the grease zerk fine. Applying grease was great. So far I have needed to use a pry bar to get it off of the zerk. So far only used on hard to access zerks, will have to try on an easy to access zerk to see if it is any easier to remove from the zerk.

I used this in my 2017 Chevy Duramax. Works great for for 2 zerks that I cannot get to with a traditional coupler. Positive seat to gun and to grease zerk, you can hear and feel the click. A little touch to get off but I will take that vs falling off.

Securely snaps on fittings so grease does not leak out around the sides during lubrication and is also easy to remove. Quickly attaches to end of gun.

Perfect for tight places

This thing didn't last long. It liked to get stuck on zerks and eventually got a zerk stuck in it. Not worth the hassle for our purposes unfortunately. Waste of money.

I have two grease fitting on my 14k trailer that are right behind the brake hubs. Even with removing the wheels, the suckers are hard to reach. I used this fitting and a crow bar wedged between the wheels and grease fitting to guide the fitting onto the zerk. Worked like a charm.
