Grease Cap Recommendation for a Trailer Hub

Question:

I used a tape measure and the cap looks like 2 3/8inch 2.375 would the RG04-080 2.44 be the correct one ??

In order to know what grease cap you would need you need to get an exact measurement with a dial or digital caliper. Tape measures aren't accurate enough since you are looking at the difference of .07 of an inch.

If it measures 2.44 the part # RG04-080 would be the correct cap. Most likely this is what you have but I attached a page that has all of the caps we offer, select your outer diameter needed from the filters.
