Abstract: The extension for top of refrigerant can for dispensing without a valve is used for supplying refrigerant to the air conditioning unit of a vehicle using a conventional refrigerant charging hose. The extension allows the contents of the refrigerant can to be delivered without having to attach a conventional shutoff valve to the canister. The extension includes a seal over the opening in the refrigerant can with a valve stem that extends through the center of the seal. The extension includes an actuator cap that fits over the seal on the top of the canister. The actuator cap houses an actuator for releasing the contents of the container. The actuator has a depression tab that is hingedly connected to the interior of the actuator cap for releasing the contents of the canister into the charging hose that is secured to a threaded projection on the front of the cap.
