On a standard zerk coupler, you can unscrew the outer housing which will put less squeeze on the inner jaws that hold onto the zerk. Ive had to adjust them in the past so that they hold on enough to not leak, but will let go when finished. These were Lincoln couplers I believe. The outer adjustable sleeve can be VERY tight to adjust from the factory, almost to the point where it feels like its going to break or strip out.So i got the k32 delivered today. Put a tube of green grease in and so far so good. Only thing is the tip once locked on does not let go too well. I had to completely unscrew the end so it would release the zerk!
I like the lock n lube tip but it seems huge and i already have some tight spots. Any other brand you can suggest
I have a Lock N lube and its really large for any recessed or protected zerks. Its awesome for ones you have access to however. For the recessed ones I have a Univerco coupler. It locks on but more like a air coupling than a Lock n lube. It fits just about everywhere a standard zerk will fit. Lock n lube have an extended coupler that is supposed to be for deep holes, but the same problem with the large OD is still there because of the LnL's sliding sleeve mechanisim. LNL is definitely easier to remove than my Univerco though so it does have its place

Too bad I didnt see this post earlier when you ordered. Macnaught makes a lock on coupler that is supposed to be "the narrowest one available". You could have ordered it with the gun and saved postage, they offer it in a kit with gun for reduced cost as well! I cant speak to the Macnaught coupler directly, but Ive sold other Macnaught products in the past and their stuff is very well made IMHO.
