Iwata quick couplings


Air-Valve Autobot!
The other day I played with a friend's original Iwata branded quick couplings. Get your mind out of the gutter. :)

Anyhows, female part fits house fine and male part fits airbrush fine and the two fits each other 100%. BUT, 3rd party males does not fit the Iwata females but Iwata males fits 3rd party females. The opening of the Iwata females are narrower then it's 3rd party counterpart. Anybody else experienced this?

No not really. I do have some that have more tendency to leak air though if they are pulled at an angle.
