I've been trying to find a good grease gun coupling that works like it should for years and have no luck. I have an old grease gun I bought at a garage sale 10 years ago that has a simple looking "Alemite" coupler on it that works perfectly. You lightly snap it on a zerk and then you can let go and pump away with no fear of it leaking or coming off even when standing on the gun handle to break a stuck zerk loose. Then you pull it off easily and keep going. The problem is I have 4 grease guns with different grease and I have to keep moving it between guns because I can't find a coupler that works as good. I'm tempted to put QD hydraulic fittings on each gun.

I've tried Lubriplate, Lincoln, and the replacements for the M18 gun (https://www.amazon.com/Milwaukee-49-...a-6185fb77bc58) and they are all just about as bad as the other. The Lincolns aren't as bad as the others. The M18 couplers are pretty much garbage. Really hard to push on, then they leak anyway. I even tried with a new zerk on a stubborn pin and they leak as soon as you build pressure if you aren't holding it on tight.

I've seen the lock on couplers but they would be in the way and someone has to make a normal sized coupler that works?
 
Your fucked: I agree with you that the old Alemites are good. I have tried them all and the lock-in lube is by far the best. I prolly get 2-300 tubes before o have to replace the seals on it. Suck it up and buy one. If you can’t get it on where you need to put remote grease lines on and be done.

I have prolly 1000 grease fittings on all my shit. I have 5 that cannot get a remote line and a lockinlube is a pain. These are to grease the input seal on a screen box.

Not sure how the LockNLube get in the way for you but they’re what I use on my guns. I really like them and haven’t had issues with them getting in my way.

x 2 for the Lock & Lube. Bought a couple regular ones from NAPA just to end up breaking the nipple off the fittings just getting them off. No problems with the Lock & Lube.
 
I'd consider the lock and lube the last resort for me. Relocating zerks is a silly solution to nobody making a coupler that works as good as a 30 year old garage sale coupler.

That’s a big nope. All it takes is one stuck fitting, and you pop the coupler off to wreck them. I agree it’s stupid but give it a try. I asIo agree Relocating zerks is stupid when the oem puts them in a retarded location.

How do you figure that a hyd coupler will be any better to fit in there than a locknlube?

The hyd coupler would go on the gun and I'd just have one hose/coupler assembly.

I just greased up my mini-ex, dump truck, and tractor last weekend and on each one there are at least 4-8 zerks that a coupler that was any longer I think wouldn't be able to fit into the space due to an arm or linkage being in the way. I bought an assortment of zerks off of the amazon and will try putting angled zerks in where I can for better access but it still irks me that all the couplers I find now days are complete garbage or huge. Sure, if I had the time it would be fun to run brake line and soft lines to each fitting so I can grease everything from a single spot like our old deere haybailer had from the factory but I suspect that like the old hay bailer, half the lines would get ripped off and have regular zerks put in at the points of use quickly.

For the record I have a locknlube coupler on a gun at work and it works fine but it is quite bulky comparatively.
 
Sounds like you need to order some 1/8” npt m-f extensions some street 45 and 90 possible a few aeroquip street 90, to get the fittings in a better location. I have a grease fitting drawer stocked full of this shit. It’s the joys of owning heavy equipment

I broke down and bought a die set for my hose crumpet to crimp 1/8” npt ends on Parker parflex house. 500’ of hose and 100+ ends later we can now grease the machines while they are running.

Lol forgot to say now that you talked the coupler all up it’s gonna fail the next time you use it lol:flipoff2:
