Abstract: An aerosol UV dye cleaner. In a described embodiment, an apparatus for cleaning UV dye from an air conditioning system includes a UV dye cleaner, a propellant and an aerosol can having the cleaner and the propellant pressurized therein. The apparatus is particularly useful in servicing automotive air conditioning systems in which access to system components is restricted.

Abstract: A refrigerant charging tool. In a described embodiment, a refrigerant charging tool has two separately formed handles pivotably attached to each other. One of the handles has a container piercing member mounted thereon. Interchangeable spacers are configured for attachment to the other handle, so that a selected one of differently shaped containers may be biased against the container piercing member when the handles are pivoted toward each other.

Abstract: An air conditioning system flush solvent and associated method of flushing air conditioning systems provides enhanced removal of moisture in air conditioning systems. In a described embodiment, an air conditioning system flush solvent consists essentially of a proportion of heptane less than or equal to approximately 70% and a proportion of isopropyl alcohol greater than or equal to approximately 29%.

Abstract: Methods and systems for dispensing a product from a container into a tire are provided. In a described embodiment, a method of dispensing a product into a tire inflation port includes the steps of attaching a flexible conduit to the inflation port and then operatively attaching the conduit to container of the product. A system for dispensing a product into an inflation port of a tire includes: a container having the product pressurized therein, and a valve selectively permitting and preventing flow of the product from the container; and a conduit assembly including a flexible conduit extending between a container connector and a port connector, the container connector being configured for connection to the container for flow of the product from the container into the conduit, and the port connector being configured for connection to the inflation port for flow of the product from the conduit into the tire.
