u/Squawk_7777

I didn't know where else to post this, so apologies in advance if this is misplaced. I am new to air tools and I can't figure out those two different formats. One tip has a diameter of 7.9mm, the other is 9.8mm. I assume one is a US and the other a EU standard. Amazon doesn't seem to have a 7.9mm female to 9.8mm male adapter. Do you guys have any advice if such a piece exists?
