ABSTRACT:
A closure assembly having an O-ring seal which produces extremely low break-out friction is provided. This is achieved by utilizing an annular endless groove which is wider than the material diameter of the O-ring in a first fitting and a flared distal end in a mating second fitting, which permits the O-ring to simultaneously compress and roll, thereby allowing for a much tighter seal than conventional O-rings' seal with out easily rupturing the O-ring.
