West Marine Pure Oceans -60° (-51°C) Marine Antifreeze provides the ultimate in 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-died purple color provides excellent blow-through visibility. Formulated with nontoxic, virgin Propylene Glycol (35% Blend), it is tasteless and contains no alcohol. This product is ready-to-use; do not dilute it.

• Provides burst protection to -60°F (-51°C) and freeze protection within a range of +7°F to +10°F (-14°C to -12°C)
• When testing with a refractometer or with a hydrometer designed for use with PG, freeze point readings on the PG scale will range from +7°F to +10°F

Note: When winterizing water systems in regions where temperatures can fall below -10°F (-23°C), we recommend using West Marine Pure Oceans -100°F (-73°C) Marine Antifreeze.
