An injection device () injects a dispensable fluid material (), for example, a liquid sealant, into refrigerant lines of an air conditioning or refrigeration pressurized system, by utilizing the pressure difference between high and low pressure zones of the pressurized system. The device comprises a tube () which contains the dispensable fluid material () and is closed by an outlet valve (). A movable member () houses a spring-loaded check valve () and is disposed downstream of and spaced from the outlet valve (). The movable member () is movable within a passageway () formed in an outlet tube connector (). Upon being connected to a service port () of a pressurized system by an installation nut (), movable member () is forced into engagement with the outlet valve () to open it to dispense fluid material () into service port ().
