The Rx11 Starter Kit consists of Rx11-flush Liquid, Rx11-flush Liquid Tank, Rx11-flush 24 Hose, and Rx11-flush Gun. Rx11-flush is a unique solvent that has been engineered for flushing refrigeration and air conditioning systems. Its patented HFC based solvent formulation is powerful enough to flush away sludge, carbon residue, oils, acids, water and other particulate. This makes it ideal for system flushing after burnouts, retrofits and for flushing line sets for R-410A conversions. It is non-toxic, non-flammable and is non-ozone depleting.
