Economical antifreeze for potable water systems, ballast tanks and sanitation systems.
Winterizing your boat’s potable water and sanitation systems for the off season is an excellent way to protect your investment and avoid costly repairs in the spring. Seafit -50° (-46°C) Marine and RV Antifreeze provides cold weather protection for drinking water systems, ballast tanks and sanitation systems. The bright pink color informs users when antifreeze has traveled through water and sanitation system lines and also serves as an indicator when flushing systems in the spring. Seafit Glycol/Alcohol antifreeze is not for use in engines. For winterizing potable water systems, ballast tanks and sanitation systems, this blended antifreeze provides an economical solution.
- Meets industry standard for burst protection in copper pipes to -50°F (-46°C)
- Ready to use—does not need to be diluted
- Safe for potable water systems
- Provides freeze protection within a range of +6°F (-14°C) to +10°F (-12°C); for colder regions we recommend using non-toxic Pure Oceans antifreeze with a -60°F or -100°F rating—see our Antifreeze 101 for a complete guide to selecting the right antifreeze for your climate and application.
