Joe,
O-rings are not usually designed to seal flat surface to flat surface. In
most cases a groove is used to retain the o-ring position. O-rings do not
form a perfect seal, there is almost always some leakage, unfortunately NASA
now understands the ramifications of this dynamic. So ... couple the leakage
behind the o-ring and the fact that it is not grooved in place and you get
walkin'.
