Abstract: A multi-profile adapter assembly is disclosed for connecting a pressurized fluid source to two or more different fittings. The adapter assembly includes an injector connector removably attachable to a hose connected to a pressurized fluid source and including an internal conduit for channeling a flow of pressurized fluid. An inner housing is connected to the injector connector and includes a channel leading to a second opening and a cavity configured to receive an access fitting on an AC system. A one way valve controls flow from the conduit in the injector connector into the inner housing. An adapter is connected to the inner housing and includes a first contour configured to engage with a first fitting and a second contour configured to engage with a second fitting. The inner housing and adapter are movable relative to one another for changing the location of the first contour and second contour.

Abstract: A process for applying a fluorescent leak detection dye to a component of an air conditioning system. The process involves the steps of (i) providing a fluorescent dye that is solid at room temperature, (ii) exposing the dye to an elevated temperature to melt the dye into a liquid or flowable state, (iii) injecting, channeling, spraying or placing the flowable dye into or on a component or an HVAC or A/C system, (iv) allowing the dye to resolidify in or on the component, (v) attaching the component to the HVAC or A/C system, and (iv) dissolving the resolidified dye in a liquid/gas.
