a connector having a support surface that defines a recess, the connector being configured to connect to the container;
an attachment member having an inner surface, a lumen, a first end configured to be connected to the delivery device, and a second end connected to the connector; and
a sealing element disposed in the lumen between the connector and the attachment member, the sealing element comprising:
a shoulder configured to engage the inner surface of the attachment member;
a flange having a lower surface extending radially along a lateral axis transverse to a longitudinal axis of the sealing element, the lower surface resting directly on the support surface of the connector;
a foot section extending longitudinally from the flange, the foot section being received within the recess defined by the support surface of the connector;
a cylindrical body extending longitudinally from the shoulder to the flange, an outer diameter of the cylindrical body having a substantially constant diameter; and
a sealing head extending longitudinally from the shoulder, the sealing head defining an opening that is configured to transition from a closed state to an open state when the cylindrical body deforms; and
a cylindrical section extending longitudinally from the sealing head to the shoulder,
wherein an outer diameter of cylindrical section is smaller than the outer diameter of the cylindrical body,
wherein an outer diameter of the shoulder is larger than the outer diameter of the cylindrical body, and
wherein an outer diameter of the flange is larger than an outer diameter of the foot section.
