Never Leaks...no wait, that's a good thing.
I've always had Cup Seal leaks after my gun jackhammers to a halt when my 20oz would run low; NW's Black Magic Cup Seal doesn't leak even when THAT happens. It doesn't leak at incredibly low pressures either. IT NEVER LEAKS! THAT SOUNDS CRAZY! I'M BRIAN FELLOW!!!
Do you like it when your CupSeal leaks? I sure don't either...wait, I got an idea, why don't you go out and get NW's Black Magic Cup Seal!
