Smaller than NO 80 nipple?

[Dieseldoctor]

So i have some generic grease guns with loader nipples for bulk filling they're not the no 80 that i got with my zeeline 5 gallon grease bulk pump. Just curious if anyone knows what the smaller loader nipple is? cant find any online just list no 80 as std?

The #80 loader nipple is the only one I am familiar with.

Are you sure the ones on your generic guns are loader nipples and not bleeders? Can you post a picture?

I did some searching they'res an american (.58") and a European 9mm loader fittings..only one i've found to take both is from grease safe.. im assuming the #80 is american? not sure which one is on my lincoln continuous flow grease gun it's smaller longer and thin vs the fat one that came with my bulk grease gun filler
