Claim 9:
10. A method for connecting a coupler and a port to allow passage of at least one fluid, the coupler comprising a body defining a radially outward facing surface, an opposing radially inward facing surface, a plunger needle fixed to the body, and a threaded portion extending circumferentially around at least a portion of the radially outward facing surface, the port comprising a threaded portion extending circumferentially around an inner surface and a Schrader valve, the method comprising:
securing the threaded portion of the coupler to the threaded portion of the port;
compressing the Schrader valve of the port with the plunger needle of the coupler to create a channel between the coupler and the port, the channel configured to permit the flow of the at least one fluid between the coupler and the port; and
passing the at least one fluid from the coupler to the port through the channel;
wherein the coupler comprises a first O-ring on the radially inward facing surface, the first O-ring configured to create a seal with an outer surface of the port.
