Is there such a thing in real life? I am having a heck of a time finding them locally. Maybe I should try grainger?

Does anyone use these or think they make a difference in allowing more cfm and less pressure drop or are they just "hyped up snake oil" ?

Thanks

Yes the high volume air fittings do make a lot of difference on hvlp spray guns. I don't know what area you are in but in my area in NC most of the auto paint stores sell them. If there is a NAPA store in your are I know they sell them if they don't have them in stock they can get them from there ware house. also
Hope this help

I read your post and couldn't help myself. Any valved quick connect will have some affect on pressure. I usually go with a larger quick connect to minimize this effect.
