Camco Freeze Ban -50 protects your boat's fresh water system from expensive freeze damage by inhibiting fouling, corrosion, and algae growth.
Helps lubricate pumps and valves throughout the system. Freeze Ban is a propylene glycol-based antifreeze formulated to protect down to -50 deg F even though some slush/semi-solid formation is normal.
Use Freeze Ban at full strength; no dilution or mixing required. Safe for drinking water systems, copper, brass and all types of plastic except acetate. Can also be used full strength to winterize boat engines.
