The Fulton Grease Cap, part # F001609, is the closest grease cap I will have to 3 inches. The flange diameter on the cap measures 3.125 inches. The overall height is 1.31 inches.
There are 2 ways to determine which replacement grease cap you will need. The first would be to measure the inside diameter of the hub where the grease cap install with a dial caliper and then match up measurement to replacement grease caps (see link).
The other way would be to remove your hub assembly from the trailer and look to see what bearing and seal numbers you have.
If you can send me the inside diameter measurement or the bearing and seal numbers, I can recommend the correct replacement grease cap.
