grease fittings for 03 Ramlin trailer bearings

[obd666]

anyone know where to pick up new zerk fittings to grease the bearings on an 03 ramlin trailer? they are the small ones that are barbed on the end, not threaded. they come off in my grease gun and i destroy them getting them out. the local hardware and auto supply houses have plenty of threaded ones that are too big to screw in. the smallest i found was 1/4-28 threaded. i know i could just change the entire cap, but would rather avoid it. any ideas?

well, the ones with the barbs are termed "drive type" fittings ... now to figure out which one it is and order a handful

are possibly these from dexter axle. says they are 1/4-28 too but they look much more tapered

for future reference, it ended up being a 3/16th drive fitting. specs and pic below ...

Thank you, I need some for my 02 trailer. Did you order from Dexter?
