Does the LockNLube coupler snap onto the lower ball joint zerks of the "classic" Silverados and Sierras? I always have trouble with grease leakage there on my '05 2500. It was the same on my '02.

The "chinese knock off" looks better built to me going by just the pictures. The $30 part uses mostly stamped metal (handle, pull back mechanism on locking ring, bottom lever point), where as the $18 one has more serviceable pieces should something break (screws, rivets, thicker locking ring, thicker handle). Either of them would probably last a very long time for home service.

ok inside the clamping of the lock n lube,,it has a piece that tightly seals to the fitting,chinese knock off doesn't.plus the lock n lube has extra clamps for a rebuild if needed.

Are you getting that from the image, or do you have one of the cheaper ones? I couldn't find any pictures that show the inside of the tips to see what the seals look like.

From the back of the package on another listing...

... Multi-Year Service Life: High-Performance Hydraulic Seal ...
I really don't see how any grease nozzle could be made without a seal, the grease would never go in the zerk.

Looking at the photo and the geometry of the linkage... it looks like it's a "over-center" device. You manually push the lever down to lock it on, them manually lift the lever to release.

Screw that.

The LocknLube is springloaded, and is operated with one finger.

I had a different style chinese locking grease nozzle that you pulled back to release it like a quick connect air hose end and could never get it back off of the fitting, threw it in the trash a few years back.

Reading these posts on the Lock and Lube coupler, i see that many like the product (if purchased from the manufacturer to make sure not a knock off). However; The straight on orientation of connection to grease points seems really "long" to me.... can someone verify this coupler easilly connects to all zerks on an L5P duramax....? I will order if so but i would like to make sure. It seems to me a 90 degree coupler would be better- is there a better option from lock and lube?

I have one, and maybe it was just a few clogged zerks but it kept pushing out under pressure..

but most of the zerks I have it has worked without issues!

Thank you.
So other than clogs, the coupler connects to zerks (orientation wise) with no problem...?

oh yeah no issues!

doesn't pop off and is very easy to connect and disconnect! I had a standard coupler before and it kept getting stuck on the zerks and creating alot of unnecessary headaches!

I haven't had any problems with it on our duramaxes but have ran onto some fittings on other equipment where they were in deep pockets and I couldn't get into them to push the lever and latch them. I purchased an adapter set that fits about any fitting and position to go along with it, this thing is priceless if your greasing things by your self. I believe that they sell two different lengths of the lock n lube.
