AEA HP O ring sizes?

I measured the groove diameter of the adapter which came out to be 14.05mm and the thickness of the stock oring which was about 1.7mm and went to oringsandmore.com and ordered the Metric Buna O-rings 14.0 x 1.78mm as they seem to be the closest to stock size I could find there. They seemed a little loose when I installed the bottle adapter into the receiver but the great news is it is holding pressure and I haven't seen any leaks at 250 bar fill.

I just ordered some .. my Megalodon rear tank adapter is letting air out , and it’s depressing me . I tried other o Rings and zilch . If these end up working … my good sir , you have my gratitude and may all your dreams come true !! lol seriously thank you !
