I'm looking for one.
I've went to a couple auto parts stores locally;called McMaster Carr,I struck out.
A standard-style grease gun nozzle/coupler that's straight-in and fits Zerk/standard grease fittings.
I don't want to use a needle;I want a grease gun nozzle that locks onto the zerk grease fitting.
I want a nozzle/coupler with the O.D. measurement smaller than .540" w/ an 1/8" NPT female inlet;I want fit it into tight spaces like vintage foreign car driveshaft U-joints,etc.
I want one Made in USA of good quality,so it doesn't fall apart after the first 40 times I use it.
I don't think many modern(2000'+)automobiles even have grease fittings anymore,kinda 'run-em until they're done', then buy a new one.
planned obsolescence.
