The Great Grease Gun Coupler Showdown

[bumperm]

Gary, I don't have my Kubota or Ford here at the shop so can't veryify this. But, there were a few Zerks on the Kubota I couldn't reach with the LnL. I think the Univer-Co will work on those.

My concerns about the Univer-Co would be if the zerk is deeply located to the point that you can't get ahold of the collar to release it???

I agree about the "need". I'm 70 bucks in now. For tools that I can't claim a solid need for.

Just bought the Univer-Co coupler, already have a LockNLube. I agree, a zerk at the bottom of a hole or virtual hole would be an issue, though easily resolved with the Univer. Bend a "U" in a stiff wire to fit the smaller diameter, then a 90* to bring the wire alongside the grease gun hose or nozzle tube. Insert both in "hole", grease, pull on wire to release coupler - repeat.

I haven't used the Univer coupler either, though it appears more nicely made that the LockNLube. "Nicely made" may not affect functionality, though in this case I suspect it may. the Univer uses 5 balls to affect it's seal, the balls moving inward to engage the radial groove in the zerk fittings shank. The barrel sliding action, though spring loaded, is silky smooth. Well done!

If, for some reason the Univer fails its trials, I'll have egg or grease on my face.

Hi all,

Where are you guys buying the univer-co coupler? I did a search on the internet and ebay and haven't found a source yet.

Oh crap, I didn't keep that info. My wife would know. I Googled it and bought from one of the providers listed. I'll ask her this weekend and list the results.

I'm still using mine. Although I am developing a couple issues.

Worst is if the zerk won't take grease you have created pressure against the coupler and the zerk. It doesn't want to let go.

Second issue is it doesn't latch onto old zerks that might be worn down. An example is zerks on my recently acquired Flail Mower that are subject to wear from debris as it's cutting. I replaced them with new zerks and everything was fine.

I'm gonna squirt another couple tubes of grease thru the coupler and then make a decision about keeping it in operation.

Understand, I'm the type of guy that doesn't see a problem with holding the coupler on a stubborn zerk until I'm successful.

Try your local deere dealer. Mine has them.

Come to think of it, I think I got mine at O'Reilly's Auto Parts store.

I'm still looking for the univer-co coupler. Deere (Nortrax) didn't have it but parts guy was intrigued, says he will look into it, he wants one too. Napa and a few other auto parts stores don't have it either. We don't have O Reiiys here either. Going to search ebay again.

I have one of these, along with the LockNLube. The grease coupler is well made, and smaller so it fits in places the LockNLube won't. But, there are problems, often it takes considerable pressure to get it to lock on. I've tried it on some zerks were it absolutely, positively refused to lock (the LockNLube locked right down on that recalcitrant Zerk and did the deed with no fuss). So the grease coupler is somewhat picky. Also, in some applications it's hard to release as you have to grab that boss at the back and pull it, easy if there's good access, sometimes not so much. Nicely made, but at times frustrating.
