Isn't that a pain? It's not so much that they are different sizes, as
different patterns. When I know I'm going to buy quick connects, I always
bring along one of the males. The females look pretty much alike, but it
you hold up the different males next to each other, you will find (probably)
three different patterns. And, no, they are not interchangeable.
