Abstract:
1. A kit for urging a fluid into an air conditioning system, the air conditioning system having a tubular fitting and a first pressure-actuated valve assembly mounted within the fitting, the first valve assembly having a first valve and a pin connected to the first valve, the pin being retractable to actuate the first valve to allow entry of the fluid into the air conditioning system, the kit comprising: a charging system and an adapter, wherein the charging system contains the fluid, the charging system is deformable and non-pressurized, and the charging system has a first end with an aperture, and wherein the adapter has: a rigid body, the body having a first end for connecting to the charging system at the charging system first end and a second end for connecting to the fitting of the air conditioning system; the body having an inner surface defining a conduit within the body; the conduit extending between the first and the second ends for fluid communication therebetween; a rigid depressor mounted to the body for urging the pin of the first valve assembly to retract when the air conditioning system is connected to the body; and a seal for discouraging leakage of fluid between the body and the fitting when the air conditioning system is connected to the body.
