Prevents marine engine cooling systems and boat, RV and home plumbing systems from bursting in cold weather. Formulated with a premium additive package for maximum corrosion protection. When used correctly, it provides reliable burst protection to -50°F for drinking water systems. The non-toxic, eco-friendly Propylene Glycol formula is tasteless, and contains No Glycerin. Bright pink color makes spring-time draining virtually foolproof.
