Star brite® Winter Tech -50°F (-46°C) Marine & RV Water System Antifreeze provides cold weather protection for drinking water tanks and systems and holding tanks at an attractive price. The alcohol and propylene glycol formula will not harm aluminum, copper, brass, or solder, with a bright pink color for excellent blow-through visibility. This product is ready-to-use; do not dilute it. Star brite® Winter Tech -50°F (-46°C) Marine & RV Water System Antifreeze will provide burst protection to -50ºF (-46ºC). Because it contains a blend of alcohol and propylene glycol, neither a PG nor an alcohol refractometer will provide an accurate freeze point reading. However, a PG refractometer is still a great reference tool to ensure the product is within specifications. If your PG refractometer shows a reading between +21ºF to +25ºF (-6ºC to -4ºC) or stronger, that indicates the formula is within spec and ready to use even though the actual freeze point of this blend is much lower. Note: This product is not recommended for use in engines; the alcohol blend may evaporate more quickly than Star brite® Wintersafe -50ºF and thus could lead to less protection in late winter. To protect engines, we recommend Star brite® Non-toxic Antifreeze. Note: The burst point of PVC pipes used in most drinking water systems is about -10ºF (-23ºC). When winterizing water systems in regions where temperatures can fall below -10ºF (-23ºC), we recommend using either Star brite® -100ºF or -200ºF (-73ºC) Antifreeze, choosing the appropriate formula for local conditions. Features Safe for copper, brass and all types of plastic Provides burst protection to -50°F Propylene glycol and alcohol formula is safe for all water and holding tank materials
