- Patented process with fixed dimensional control of the air and liquid flow paths
- Air pressurizes the cleaning fluid to scrub into corners and crevices and clear trapped debris
- Pressure is regulated to a safe level when a hard blockage exists, which guards the heater core against excess system pressure
- Water line backflow preventer
- Large rubber tip for radiator necks and engine block flushing, small whip-hose tip for heater core tube stubs
