AZUNO G2 Quick Connect Grease Gun Coupler

I haven’t had these locking couplers long but so far they do the job just as expected! They hold onto the zero fittings well and don’t leak. Releasing is simple and can be done even under pressure. One thing to keep in mind is clearance around protected fittings. This coupler body is larger than a standard non-locking coupler so it may not fit into every nook and cranny you find in the field. T hear being said, it fits on all the protected fitting on my tractor and implements. The price is a bargain too considering what the big name company is charging (I got 2 Azuno couplers for what 1 LockNLube coupler costs). I will continue to use these on my grease gun and update my review if necessary. Thanks Azuno!

Really happy with this purchase. It's very good quality, ery easy to install, and works as intended. I used it on a 30+ year old grease gun and it installed and worked perfectly. The coupler locks on grease fittings and makes lubing much easier without the coupler falling off. The only negative is that I had two fittings in a tight spot that I could not lube because of the larger diameter of this coupler. The problem was solved by switching back to the smaller OEM coupler for those two fittings which was fast and easy to do.

Mislaid my grease gun. Borrowed a friends and could not get it to seal on zerks and got grease everywhere. Finally broke dow and bought new one. The first zerk I greased worked fine but couldn't get the silly thing off even with a pry bar! Ended up unscrewing the end from the gun. That's when I bought this product. Works great, grease only where supposed to. BUT the fitting is a bit fat. There is one fitting on my tractor it won't access. I will have to grind out the access hole a little bigger for the fitting to reach that one zerk.

Bought a new grease gun which worked fine except that the coupler wouldn't go on and off easily. You had to really press hard to get it on, and then pull with all your might to get it off. This coupler is really slick and well worth the price. Squeeze the lever, and it slides on easily. Release the lever, and it's impossible to get it off. Squeeze the lever again, and it comes right off. Wish I had one of these years ago.

I bought this because my regular grease gun tip grabs so tightly that I broke some zerks. In most cases this coupler works nicely. But it is just fat enough not to fit into some of the access points on both my Kubota tractor bucket and my boat lift mechanism. So now I am looking for a long, skinny adapter tube to use in these tight spaces, with a zerk on the feed end. I have found one on Amazon, but the tip end again looks a little fat. So to buy or not to buy? Just be aware. Works well, but maybe not in tight spaces. And I also have zerks on my boat lift that this will not click onto, even where there is ample space. Apparently not all zerks are the same dimensions.

Finally, an affordable solution to an aggravating flaw of grease guns. Either they won't stay locked on the zerk or it won't let go when you're done pumping in grease. Looks like I won't be adding to the grandkid's vocabulary anymore, at least in this arena. After some use, I was disappointed to realize the nose of the locking nozzle is too large to reach some of the grease zerks on my Kubota tractor. A slim version would be a nice addition to the lineup. A week after I wrote the above, I was contacted by the same folks who sold me those nozzles. They do have a slimmer version. I ordered one, and viola! It works! Both versions are of excellent quality and well worth the price.

Cheap. Wouldn’t recommend.

Works as advertised! Easy installation and even easier to use! Now I don't break off zerks.

Excellent

Perfect tool!!

Works pretty well, can be hard to get off of grease fittings some times, and if grease fitting is recessed the head is very large and hard to get in.

Best investment for my grease gun

I find these very handy, whilst working by myself, crawling around under a car. I have a Ford Model A with dozens of grease fittings, and this allows me to accomplish a job faster and easier.
