Mercury -50°F Water System Anti-Freeze, 1 Gallon 8M0073201

Mercury -50°F Water System Anti-Freeze 8M0073201 is a ready-to-use antifreeze designed to protect marine engine cooling systems and boat, RV, and home plumbing systems during cold-weather storage. It provides burst protection down to -50°F (-46°C) and freeze protection from approximately 12°F to 16°F (-11°C to -8°C).

The non-toxic formula uses a 30% blend of virgin propylene glycol and is glycerin-free. Its corrosion-inhibiting additive package helps protect aluminum, copper, brass, and solder while remaining safe for rubber seals and hose materials. The bright pink color also provides improved visibility while flushing the product through a system during winterization.

This formula is ready to use and should not be diluted.

Recommended for:

• Marine engine cooling system winterization
• Boat freshwater and plumbing systems
• RV water systems
• Home plumbing systems
