A delivery system for discharging an atomized treatment agent into the interior of a closed mechanical system having a fluidizing gas inlet collar jointed to an overlaid gas supply hose via an ID/OD coupling joint for receiving passage of the gas through the gas supply hose into the closed mechanical system in a longitudinal direction, such system comprising: (a) a pressurized container holding the atomized treatment agent for treating an interior surface or working part contained inside the closed mechanical system; (b) a flexible conduit for delivering the atomized treatment product from the container to the closed mechanical system; and (c) wherein the atomized treatment agent is delivered by the conduit from the pressurized container to the interior location of the closed mechanical system; the delivery system characterized by: (d) a guide support for the flexible conduit, comprising: (i) a curved body at its one end; (ii) a hooked body at its other end; (iii) a channel positioned inside an inner surface along the entire length of the guide support, such channel having dimensions configured to encapsulate the exterior surface of the flexible conduit; (iv) the curved body of the guide support being disposed between the closed mechanical system fluidizing gas inlet collar and the gas supply hose with the hooked body causing the flexible conduit to extend inside the closed mechanical system with its distal end pointed in the same direction as the fluidizing gas flow; (e) wherein the flexible conduit is disposed inside the channel of the guide support, so that the guide support protects the conduit from crimping.
