Winterizing isn't the end of adventure. It's how you make sure the next one starts right. This -50°F antifreeze keeps your RV or boat's plumbing protected through the cold so your first trip starts without a hitch.


Highlights

  • Protects Your Water System During Storage: Guards against light freezes that can damage lines and fittings in RVs and boats.
  • Works With RV and Marine Plumbing: Compatible with copper, brass, and most plastics (except acetate).
  • Cost-Effective and Easy to Flush: Ethanol blend flows smoothly through lines and rinses clean when spring returns.
  • Proven Burst Protection: Meets industry standards for copper pipe burst resistance, keeping your lines intact.
  • Guards Against Corrosion: Helps protect internal metal and plastic surfaces while your system sits idle.
  • Bulk Pack Convenience: Six 1-gallon jugs provide enough antifreeze to winterize most RVs and boats.

Features to know about

What is Burst Point vs. Freeze Point?

Labels like -50°F can be confusing. That number refers to the burst point, the temperature where your lines won't burst, not the point where the fluid stays liquid. This ethanol-based -50°F antifreeze provides dependable protection for moderate climates but can start to slush near freezing, making it harder to drain your system. If you're storing your RV in colder regions or for an extended subzero stretch, step up to Prime Guard -100°F RV & Marine Antifreeze (PG96ZR) for reliable freeze protection.
