<p>I've encountered similar for years (glad to know I'm not the only
A-R on the List ;)). Sometimes, the coupler would work fine on 10
zerks, then lock-up on the 11th (which, of course, was in the
least accessible place). There should be a spec for the fittings,
but if not the manufacturers--read: China--might all make them
with slightly different dimensions, slopes,springs, etc. (and, if
there are specs, I won't bet money all the factories in China
adhere to them). Same with the couplings, if it's in the ballpark
it ships, and with a 'tight' coupling with a slightly oversized
fitting you'd have problems getting it on AND getting it off (what
really pisses me off is when the coupler is clamped on like a gila
monster but there's not enough room to wrangle it and, if you
twist too hard well, you get the picture). It's almost a no-win,
if the coupler is too loose or the zerk is undersized, they go
together fine, but 80% of the grease don't make it home.</p>

</p>
<p>Best I can suggest is find a coupler that's agreeable and, if you
install zerks find a brand that's agreeable as well. If one
always puts up a fight, maybe file the zerk down a HAIR (though
it'll probably leak like a mo-fo). Better yet, try another zerk
and have a close look and see if you can tell a difference
(inquiring minds)<br>
