A breakseal providing desired compliance characteristics for a reliable seal between the fitment of a liquid dispenser and the breakseal. A compliant material is provided on the non-wetted face of the breakseal, enabling compliance of the breakseal on a wetted face for sealing between the breakseal and the mating component. The breakseal may also include raised features on segments that are separated after rupturing that prevent or mitigate scoring of O-ring seals upon probe insertion. A wiping feature that provides redundant sealing between the breakseal and a mating cap or other mating connection may also be incorporated into the breakseal. The breakseal can also include a flat on an outer perimeter that may serve as a gate for injection molding, so that any gate vestige from the molding process will not protrude beyond the outer diameter of the breakseal to cause unwanted interference between the breakseal and the mating connection.
