I have one and it works great . I have to use it on idler arm on a couple of my G.M. trucks . I screwed it on to a pipe , put a zerk on the other and snap it on to my grease gun hose . :thumbsup:
That's exactly what I'm talking about using it on, thanks. I like to lube every oil change, but that one cussed fitting is absolutely aggravating...the other day I was standing out in the yard, hands covered in grease ranting and raving at the truck when I realized "Duh, somebody has to make a 90 deg coupler or something!" I'm embarrassed that it took me that long to figure out the simple/obvious solution.
