Premium -50F Propylene Glycol Anti-Freeze Gallon #74-31400 Star brite -50°F (-46°C) Non-Toxic Antifreeze provides excellent cold weather and corrosion protection for drinking water systems and all engines. Its premium additive package prevents corrosion of aluminum, copper, brass and solder, but will not harm rubber, seals or hose materials. The 3X-dyed bright pink color provides excellent blow-through visibility. Formulated with virgin, non-toxic USP-grade ingredients. It contains no alcohols. This product is ready-to-use; do not dilute it.
Star brite -50°F (-46°C) Non-Toxic Antifreeze will provide burst protection to -50°F (-46°C) and freeze protection within a range of +12°F to +16°F (-11°C to -9°C). When testing with a refractometer or hydrometer designed for use with propylene glycol, freeze point readings on the PG scale will range from +12°F to +16°F. Note: The burst point of PVC pipes used in most drinking water systems is about -10°F (-23°C). When winterizing water systems in regions where temperatures can fall below -10°F (-23°C), we recommend using Star brite® -100°F (-73°C) Non-Toxic Antifreeze.

Use in boats, RVs, vacation homes, pools
