  • Rated to 10,000 PSI! Locks on, stays on. Does not leak once locked on.
  • Hands free - does not pop off under pressure. Easily release from fittings with the thumb lever, even at extreme pressure.
  • Fits all standard Grease Guns - 1/8 NPT fitting. Fits all SAE and Metric Zerk fittings. Simply replace your existing coupler.
  • Over 3.5" of reach. Great for shielded PTO shafts, axles, harvester heads, U Joints and other recessed grease fittings.
  • Includes rebuild kit. Easily replace seal and jaws without replacing the coupler.

The LockNLube Grease Coupler XL, just like the shorter original, is compatible with all grease guns and grease fittings.

  • It doesn't leak once locked on and will not pop off under pressure.
  • No hands are needed to align or hold the coupler in place while greasing. You have both hands free to operate your grease gun and know that the grease will go in, not on, your machine.
  • The XL is suited for all machines, but especially useful for U-Joints, Harvester Heads, shielded PTO shafts, and any fittings buried deep behind a shield. With 4" of reach, you can be confident that you'll reach your fittings and grease will go in, not on, your machine.
  • When you want to release the coupler, simply depress the thumb lever, even at extreme pressures.

Like having three hands. For me it worked perfect. The only fittings I could not get on were grease fittings that are in a barrel like area like my Kubota front loader bucket. The unit does seal very well with grease going where it suppose to , in the fitting not around the fitting. I thought it was too pricey when I ordered it but after using it I am glad I bought it.
UPDATE: I was wrong. After taking a better look at those barrel like fittings and cleaning them properly the tool does fit inside. That even makes it SIX STARS to me.

I really like this coupler. I am able to get at the recessed grease zerks on the loader arms on my skidsteer thru the holes in the frame with this grease coupler. I had bought the shorter version of this coupler first, and it wasn''t long enough. I combined this coupler with an 18v electric grease gun, and it works pretty slick. I have found that I can get (3) complete greasings of my skidsteer and the attachment on (1) tube of grease. It is a little tricky sometimes to get the tip of this to lock onto the grease zerk, but once the tip is locked, the device works very well. I paid $40 for this, which seems to be a fortune. The time that it, combined with the electric grease gun has saved me, has made it worth it. And by time, I mean not only the clock time, but also the convenience of being able to use one hand to lock this onto a grease zerk and run the switch on my electric grease gun with the other hand. I recently badly injured (2) fingers on one hand, so I couldn''t have gotten this device at a much better time. If you can stomach shelling out $40, definitely buy this device. I put the shorter coupler ($30) that I bought first on a manual grease gun as a backup.

BOTTOM LINE: Awfully pricey for a grease gun tip ...but what a time/hassle/grease saver!!! After just a couple of uses I was kicking myself in the butt, wishing I''d bought one decades ago. Worth every penny!

THOUGHTS: When I happened upon this clever little gizmo while surfing Amazon I just knew I''d end up buying it. Only diff from my initial online looking was that I opted for the longer tip, to more easily reach the underside of my lawn tractors to access pulleys, hubs and other difficult-to-reach zerk fittings. This thing is one of the greatest inventions in the history of ever. If you use a grease gun on a regular basis (hand, electric or air) you will save a lot of time and hassle (and grease!) by using this locking tip. It isn''t without its pains and it isn''t 100% perfect all the time, but it has already paid for itself and then some as far as I''m concerned. A frustrating afternoon of nasty filthy work was reduced to just a few minutes'' worth of wiping, clicking, pumping & clean up. When you take into account the amount of grease (which, depending on what kind you use, can get very expensive very quickly) that you''ll save by not accidentally pumping it all over the floor of your garage or onto your lawn then this ingenious tool truly does pay for itself. Consider me converted! I''m recommending this to every DIY''er I know.

I must say I was skeptical because it looked to big in diameter to get into U-joints and other spaces, and I have fought grease Zerks for so long I just thought it was to good to be true. Well it is true that this is a game changer, locks on perfectly and even at an off angle of about 10 degrees, that frees up a hand to do whatever you need it to do, I used this with my battery grease gun. so I could hold a flashlight or whatever. the even better part is when I serviced my 18 ft triple deck bat wing mower that has almost 100 zerks it used to take at time 4 hours, 4 tubes of grease and a roll of paper towels. I was able to fly through it using less than 2 tubes of grease 4 individual paper towels and less than 2 hours, there was no waste, no fighting zerks, no messy grease everywhere. and the tip fit easily into U-joints and drive shafts ect. If you don''t have one of these yet your missing out.

My backhoe has around 50 grease fittings. It normally takes 45-50 minutes to grease and almost always costs me grease on my jeans. With the Lock and Lube my time to grease the backhoe cut to around 15-20 minutes. Beside the fact no grease on my jeans. Try to hold the end of grease gun hose fitting with left hand. Then put the canister on my left thigh to hold and pump with my right hand. This time, place the Lock and Lube on the zerk fitting and pump with both hands . So easy! I wish I would have done this years ago. Last thing. I''ve received messages from Lock and Lube. Any issues what so ever, let them know and they will take care of it. How nice. Not only made in USA but made to last years. I promise you will love it!

"Good" doesn''t quite do it! This is a treasure of a tool. Working on excavators and tractors where you''re having to reach awkward places can be cramp inducing, greasy, messy work...especially when you have to hold on to the lube end of the gun. Getting to lock onto the zerk, and not worry about the coupler coming loose makes the job so much easier, less messy, and less stressful. The cost made me hesitate. The reality of what it does makes me think it was one of the most worthwhile purchases I''ve ever made. I''d do it again (and probably will) in a second, if I need to.

Sometimes you have to spend a little to save a little. With this product, spending $40 is saving me hours of aggravation greasing my tractor -- and I''m not getting covered in grease!

I have a cheap grease gun, and since becoming a tractor owner a few months ago, have been struggling to do the recommended greasing every 10 hours of use. It was difficult to get the gun connected to the 20+ zerks I had to grease, and even more difficult breaking it off the zerk after squeezing in the grease. After about 2 hours of work I was aggravated and sore, with a few bloodied knuckles, and grease smeared all over my hands and clothing.

I finally sprung the $40 for the LockNLube coupler (the long version) and it worked flawlessly. Seems to be built with quality, solid feeling materials. And comes with spare parts when the original pieces wear out. I was able to grease the zerks in about 10% of the time it took before, without getting grease all over myself. I choose the long version to reach into some difficult spots, but if you have easy access to all the zerks, the $30 regular version will be fine.

I''ve been recommending this to everyone I know who has to maintain equipment. At first I didn''t like the idea of spending $40 for the coupler when the grease gun itself only cost $15. But it has been one of the smartest things I''ve ever done. Well worth the cost to make equipment maintenance so much easier.

Simple design and works beautifully. The coupler opens easily and closes/locks over the zerk fitting. No more force inserting or removing from the fitting. No leaks found after an extensive tractor grease job.
I''ve read other reviews saying that this coupler can fail, and I don''t doubt what these other folks experienced. However, the company also must have read these negative reviews because they now give you a set of spare replacement parts for the tip - included with the purchase.
This coupler solves a major problem with zerk fittings either popping off during grease feed or breaking off completely when removing the gun. The LockNLube is so clever and useful that even if it does eventually fail, I would buy another.
