Will Fulton 1.96 Inch Grease Cap Fit Hub and Drum for a 3,500 Pound Trailer Axle

Question:

Does this Grease cap fit a 3500 lb standard brake hub? I know they are 1.96 and the ones for a 3500lb are 1.98. Only asking because I need a shorter one to clear wheels.

I tested a Fulton Grease Cap # F001610 in a standard 3,500 pound axle hub and drum assembly out in our warehouse. The cap just drops right in and would fall back out immediately. You will definitely need the 1.98 inch caps # RG04-020. They are about 1/4 inch (0.26 inches) taller than the Fulton caps.
