I have to ditto all of the positive comments on this product. As someone who owns several pieces of excavating, farm, and landscaping equipment, I don’t know how I ever maintained al of this equipment without this fitting. Sure saves a lot of wasted grease, busted knuckles, and language that as they say, would make a sailor blush. Although I ordered two the first time, I just ordered another one.
My tractor and attachments have MANY grease fittings that need to be serviced every 10 or so hours.
This fitting makes greasing my rig easy and clean with no grease squirting all over the place. Just lubed the u joints on three drive shafts and there was no mess and I am sure they got the necessary lube.
Sure wish I had this many years ago.
Diamètre 15mm comme un coupler standard Ingersol. 17mm au niveau de de la plaque soudée de commande. La perfection n’est pas de ce monde sauf dans celui du graissage grâce ce à lui. Utilisé sur quad Can Am Out 400 en particulier sur cardan arrière Parfait. Facile à positionner, à clipser, pas de fuite, et à retirer.
Every grease gun should come with one of these. Holds on the fitting like an eagle with a salmon in its claws. Good for fittings that are slow to fill. If you can’t get grease to flow – it’s probably because the fitting is bad and needs replacement.
Not something everyone needs, but if you need a coupler to put grease in stubborn joints this is the one.
My experience is most bearings will take grease with a regular coupler. This coupler is for the rest of the places grease is needed, that require extra pressure to get it there. Tractors, loaders, dozens stump grinders, where the least amount of dirt, even with daily greasing can plug up a joint. This coupler puts the pressure to the line and gets the grease to push debris back out.
$30 is cheaper than the labor to tear down most joints, let alone re-bush, or oversize a joint. I bought this after refurbishing my machine. I wanted to be certain the grease is getting to critical locations. I must say, even after the rebuild my gun pile up grease at the fitting, so I ordered this. With no other changes, this coupler pushed the grease thru the lines.
This $30 will keep me from doing another overhaul.
I can’t believe I even questioned buying this. Hands down the best tool in the toolbox. Grease guns are useless without this. Makes greasing my Kubota a breeze. I should have bought 3 and given them to friends.
It’s the best , built to last, liked it so much I got my wife one, got to keep her lubed up.
Great addition to grease gun. Really works well. No need to try and hold on zerk in unreachable places. Excellent!!!
100% worth the money if you have plenty of grease lubing to do. I was sceptical when buying the first time, but now after using it everyday during harvest season to live the combine, header, tractor, and tractor-trailers using a battery powered gun, I am going to buy one for every grease gun we have!
The only time I have had any leaks is when I did not get the coupler on the fitting tight, which has been rare.
This coupler has made my job so much easier in the mornings.
And now just found out there is an XL version too!!

I have several of these now and they are worth every penny I have paid. I have a lot of farm equipment to grease and I have an assortment of grease guns, some with flex hose, some not, some air fed. My biggest complaint with the standard adapters that come with all of these products is the amount of fine tuning required to:
1) either get the thing to stay on the grease fitting
2) to get the darn thing off the grease fitting when you are done.
I have busted my knuckles many, many times pulling the grease gun off and having it come loose and bust my hand up. The flexible hoses are the WORST. I no longer have any of these problems. Gone. Done. Never to be seen again. This thing does not leak, it does not come off by itself, but it DOES come off very easily when you want it to. This past week I used a flexible tube with this nozzle to pack a bunch of wheel bearings in one of those inverted cone contraptions. I had to exert some heavy force to get the grease down thru the bearing. The coupler stayed right where I wanted it and in fact I could lift the cone up using the coupler to see if the job was done.
The size of the adapter.. Some fittings are thru a small hole down inside the machine and there is no way to get this into the hole or get your hand in there either. But that is a small percentage of the fittings I have to deal with.
Cost. Yes, it is a bit expensive, probably costs more then the grease gun you own. But it is worth every penny in my book. I currently own 4 of them.
These work amazing. Wish I would have know about this product sooner. They lock on will not come off and can handle any type of pressure.
If you need a heavy duty grease this is what you need grease and will move grease through anything.
“The grease gun is used across our full product range of Volvo Construction Equipment. Our clients have praised the grease gun’s efficiency, reliability and ease of use, even in the harshest operating conditions.”
I am a 5’3″ woman. I have arthritis in my hands, and I own a Crane.
I was continually frustrated using my Lincoln Cordless Grease gun with greasy hands, trying to hold the grease gun tip on the zirk.
There is one task where I need to grease the turret of the crane while operating the swing function, hold the gun, pull the trigger and hold the grease fitting tightly on a zirk and its is really a contortion act to pull that off. Of course there was always a mess of grease to clean up!
I mentioned this problem to a family member who recommended LockNLube. I purchased it, and it was quick & easy to replace my old grease tip with this. It was very easy to latch onto the zirk, grease the fitting, and easy to release, plus NO wasted grease to clean up.
This is exactly what I needed. If I can manage it, anyone can.
As always, I am skeptical of buying over prices items. I have tried top of the line manufactures grease coupling to no avail. So when I read about this one I figured my $30 all but gone.
I was wrong, this is an awesome product that is worth every penny.
The company gives you the pay back period in terms of % wasted grease vs the cost you pay for grease, but the fact that parts are actually getting greased makes up the $30 with just the first fitting.
I have only reviewed a few product in my life because most products are not worth my time talking about, but this product deserves my time.
We have an excavator, Dozer and Articulated haul truck, not to mention our normal tractors and equipment and it saves time, grease and piece of mind on all of them. Great product.
This is easily the best grease gun made. It also makes more pressure and will put grease in stubborn fittings that don’t take grease with a hand pump gun. Quality is excellent. Holds approximately a half of a 5 gallon lug of grease. Does not leak all over like every other grease gun. I will never go back to the old cartridge guns. With two people, you can grease a machine in no time and move on to the next and next and next all without running out.
Filling is pretty much sitting down for 15 minutes and filling with a trowel from a 5 gallon lug of grease. It is also pretty heavy when full.
Using this actually brought a tear too my eye. Never has it been so easy to grease our machinery. It used too be that if you talk about greasing a machine it was like starting a fight with your wife and you didnt want to go near it. Now greasing with the G.Coupler its like taking a walk in the park!
In all seriousness, this wee product might be costly compared too the cheap heads at 2.50 but the G.Coupler will save you that cost in the long run in grease and labour! Highly recommend!
Pumps a lot of grease under high pressure quickly, the locking nozzle works very well and I purchased extras for my hand and lever pump grease guns. I did get some of my stubborn fittings to take grease, but not all. I still found some that required taking zerks and pins out and cleaning them up to allow them to take grease. Definately works much better than hand operated grease guns.
The coupler is awesome!! Takes frustration out of greasing my backhoe, thank you!
I used to feel like dumping the grease directly on the garage floor, instead of going through the pretense of loading up the grease gun. Now, with the addition of this coupling, every single pump of the grease gun goes exactly where you want it. Brilliant.
The coupler arrived a few days after my order was placed, it’s in a blister pack. Anxious to try it out, I got a couple of wrenches to remove the end fitting from my Lincoln 1162 Pneumatic gun. Thanks Lincoln for screwing the fitting onto the male threads using a couple of hundred foot pounds of torque! Using two pipe wrenches and a number of curse words, I finally got the Lincoln fitting off and screwed the LockNLube onto the end of the hose, snugging it up with a crescent wrench.
The operation of the thumb lever to expand the collet is smooth and easy. I was concerned with the greater diameter of the terminal end but it fit nicely everywhere including pins at the bucket end of the FEL where the zerk is in a counter bore on the sleeve and into the u-joint to reach the zerk fittings located there.
Press the thumb lever, slip the collet over the zerk and release. Pump grease and every last bit goes into the fitting, absolutely no leakage. Depress the thumb lever and the head easily removes from the zerk, no resistance at all. I repeated on all the grease points for the FEL and those under the machine, same result, no muss, no fuss.
For me the cost which included free shipping was worth every penny. I have wasted a fair amount of grease on stubborn fittings and always suspected that I was not getting sufficient grease into the u-joints which would lead to early failure. This tool does the trick. It is well constructed, easy to use and does exactly what it claims to do.
I don’t like grease guns, period. They are messy, can be finicky to prime and stray grease just jumps onto me, every time. To at least have the grease effortlessly go where you want it and no where else, without having to hold or depress the hose makes me like my gun, a lot better. You either grease your machine or pay a high price later. Anything that makes this task easier, for me is a very good thing.
This is one, awesome grease gun and very easy to set up for use. Holds about 30 tubes of grease and you only need to prime it one time.
I own a landscape and tree service and always have machines to service and grease. I bought 2 of the Lock N Lube tips and put one on my mobile service truck and one in our shop. The couplers have been in use a couple of weeks and are preforming great. There is less mess and less loss of product , less cost.
I think in the time we have used them we saved 3 tubes of grease over the 2 weeks. This is a direct savings of over $10 in 2 weeks. This product will pay for its self.
We use about 5 cases of grease per month and service machines such as 60 foot JLG man lifts, Bobcats, Morebark Chippers, dump trucks , and all types of mowing equipment. The only draw back is the we changed out about 10 fittings to 90degree to get the tips in to position.
The tip is a little longer than a standard grease gun tip. This was not hard to do and was worth the time to do it. In conclusion this is a great product and will save time, money, and a messy clean up.
I wouldn’t consider going back to smashed knuckles, wasted grease and the HUGE frustration of working with cheap grease gun couplings again. This thing is a breeze to operate and began paying for itself immediately with time and grease savings. Highly recommend.
I’m so glad I took the advice of other farmer reviews and bought 2 of these right off the bat.
Have been using this for about 3 weeks and love the thing every time I put it on a fitting.
On one zerk that would not take I put huge pressure on the OTC grease gun it’s attached to and then let it hang from the zerk while shocking the joint with a hammer and it stayed put!
Also nice that they include a rebuild kit with purchase.
There is one zerk on the combine that is sunk down in a pulley where this would not fit but those types of zerks are rare.
Greased U-joints on the pto shaft for the first time without ending up with a handful of grease because the end was at the wrong angle behind the shield. Opened the jaws, clipped it on the zerk and made sure it was locked on good and purged the joint. Easy!
Cost seemed excessive until I considered how many conventional ends I’d bought over a year because those kind always leak around the outside within a few uses. With this coupler there’s a lot less grease on the floor and around the fitting itself.
Permet de graisser sans avoir a tenir l’embout et de pomper avec les deux mains, pas de fuite de graisse. Un peu encombrant pour les accès difficiles.
“My G.Guns are critical to my operations. In 10 years, I’ve never had to replace a single part and they still work beautifully. A great investment”
I saw the great reviews of the item and decided to try it.
We have an excavator that we often have grease leak out when attempting to grease our machine. Now that we purchased this we don’t have any more issues.
This thing works great and you only need one person use it. We no longer have one person pumping the grease while the other holds the grease coupler on the nipple.
I would buy again. I know it is a bit expensive but it was worth every penny
Very easy to use, clips on securely, no waste, easy to remove. Was about to buy an electric grease gun, but this makes greasing so easy, no need to, saved a whole bunch of Money. Highly recommended.
If you need to grease a lot of fittings this is a great tool because no grease escapes (less mess) so none is wasted.
I have a tractor and attachments with many zerk fittings (of slightly different sizeds) that require frequent greasing. This coupler is really worthwhile for my needs.
