The Flo-Dynamics FK310 A/C Flush Kit enables component or system flushing using any R134a A/C service equipment that recovers, recycles and recharges. The FK310 flushing process uses recycled or virgin liquid R134a stored in the A/C equipment to flush oil and debris from the system or its components. The kit comes with a surge tank, universal adapters, external filters and a hose for connecting equipment in series with the system or a component. When used with the Flo-Dynamics CCST388, the process is fully automatic.
