Ordered one from Amazon today. If it works will be worth the price.

Delivered today, fit the grease gun threads perfectly. This thing actually works great! Now I only need two hands instead of three. The one negative is the lever on the LockNLube will not fit thru the 3/4" zerk access holes on my FEL. Will need to reinstall the old connection for those or buy additional gun.

Try this, go to your local auto parts store, get a zerk with the 1/8 inch pipe thread and screw it into the old connector.

Then lock the LockNLube on to it and grease the recessed zerks! :thumbsup:

Okay I see what you're saying. Don't know if that will work? Need to measure distance from access hole to recessed zerk. Thanks for the suggestion. :thumbsup:

I posted this on a different thread about this coupler somewhere, but thought it might help with the discussion of the overall size of the unit for getting into small areas.

I measure my standard couple comparing it to the LockNLube - my standard connector was 10mm and the LockNLube was 11mm - only 1mm difference. But as said above for deeply recessed fittings, the lever will be a problem.

Yeah, it's not the diameter of the head that's the problem. It's the overall bulkiness of the entire unit. I keep a standard coupler on my primary gun. Use the LnL on a secondary gun. When it's needed, the LnL is a valuable tool and worth the cost. But too complicated, bulky and time consuming for me to use primarily.

Well, about 6 months ago I said I'd contact the company with the issue with one of my two LockNLube couplers. To review, one works great and is a wonderful product that works exactly as described, the other has a tendency to slip off about half the time. With winter, and farming in full stall, I finally took the time to follow up.

Called their toll number and I believe the owner answered to provide customer service. What a great guy! Very easy to talk with.

We had an extended discussion about the isolated issue and possible causes. The problematic coupler is an old style and the newly designed style has replaceable jaws and seal. In fact, new purchases come with a spare set of jaws and a new replacement seal included. The old style, like mine, can't be repaired or disassembled. In my opinion you'd have to do some serious greasing over many years before the coupler would need service.

Anyway, the customer service of this company is top-notch. If the slightest problem might arise, I am totally confident that it will be made right with a phone call.

For those of you still on the fence about this product, you might try giving it a go. They now even have a 30-day free trial and will reimburse $3 for postage if you decide to send it back. I'd bet you'll keep it.

LocknLube grease gun coupler ends greasing frustration.

So are they sending you a new replacement?

I've had the newer LockNLube unit about four months. Long enough to lube all the zerks 2X on the tractor. There are few recessed zerks on the FEL - its a tight fit but the unit fits and greases them also. I'm impressed - nice to not have to hold the nozzle tight to the zerk - gives you two hands to operate the gun.

I have had one of the early ones for about 9 months now and it is working great on my lever gun, with the hose from my old pistol grip.

Just ordered another one to put on the electric Lincoln. It has a hose also.

I'm glad this thread came back up. I just ordered one.

FYI, here is what I do with my grease gun. It has nothing to do with LockNLube adapter but it is what I did to make greasing anything easier. Maybe this will help other members and or this is a common thing that everybody does. I do not know. I have an original pistol grip grease gun from the 60"s which I used all of the time. Maybe about 15 years ago I added and extension hose, 3 of them in fact to the grease gun. Sure makes it easier. No need to worry about getting the grease gun into tight places. One hand on the hose and one hand on the grease gun. I thought about putting another length of hose on but this works good. I have had to replace the end hose a couple of times because it takes most of the abuse. Five or six years ago I upgraded to a air driven grease gun, a low cost from Lowes. It still works. It surprises me. Like I said maybe this hose extension stuff is a common thing that everybody does. The second item is the grease adapter. I purchased this back in the 60's for my mothers Buick convertible at the time. The Buick had a split drive shaft with a carrier bearing that needed greased occasionally and this was the adapter I bought. It is an aluminum body with an hardened tip. It was designed for the carrier bearing application but it fits almost perfectly into the ball check on a zerk fitting. I use it on those tight spots where you cannot get coupler on, AKA u-joints, axle shafts etc. Hold it straight on and pull the trigger. I am not saying you will not pop out a ball check once in a while but it sure saves a lot of aggravation. Somebody may make this style of adapter now, I do not know. I have other grease adapters but this one with the hardened tip works great as noted. Also I was never in love with those lever arm grease guns. If you want a mechanical grease gun a pistol grip to me is the way to go. Hopefully somebody can benefit from my post. Later

Updating this old post with a picture of my long extension:

My update.

Both of the locking couplers I bought are in the tool cabinet drawer. Back to old faithful, the proper adjusted standard coupler. Was a $70 experiment that didn't fit my style. That's okay. At least it wasn't $700.

Out of curiosity, what convinced you not to use them?

The LnL is too bulky and can't be used on certain zerks. While I'm swapping to a standard coupler I could have finished.

The other one, can't remember the name, if you snap it onto a remote zerk, you can't reach the release collar to get it off. So, again, by this time I should have just used a standard coupler......

My Lock n Lubes work on everything I have except the recessed zerks on my LS loader. For them I just grab my spare standard gun and do them.

I have LnLs on my Kobalt air operated gun and 2nd on Lincoln hand operated gun. Very happy with them.

I agree with you, I tried it out and it only fit about 1/3 of the fittings on my tractor, the remaining it was either too bulky or too long to use. My solution was a Milwaukee 12v greese gun. Only about $120 with a battery and charger. Now I don't care if it holds on the fitting because I can just hold it on with one hand and pull the trigger with the other. It is so quick that you don't have time to let go of the tip before you are done with the fitting. I would say it cut my time in half to greese the tractor and hoe. The thing is that it probably doubled the amount of greese I use, because now I actually greese it regularly.

You can always send them to me Richard.
