Go to
Big Creek Outfitters website and look at their "universal lubricator." This one has what looks like a regular zerk fitting. Seems to me that this could dispense just about any compound through a grease gun, like lithium. I don't understand how it would attach to a cable jacket that has no fitting on the end.
Their applications list shows it to have very broad usage, including bike cables, three wheelers, and speedometer cables.
The
instructions page has the most info.
