Hydronic RV Heat Transfer Fluid with Corrosion Inhibitors 1 Gallon

Keep your coach comfortable year-round with a propylene glycol-based heat transfer fluid formulated specifically for hydronic heating systems found in RVs and motorcoaches. It’s designed for use in systems like Aqua-Hot and Oasis, and is also commonly used in other RV hydronic platforms, helping ensure efficient floor heat and on-demand hot water.

Engineered with corrosion inhibitors, this fluid helps protect aluminum, copper, steel, and system elastomers from rust, scale, and premature wear. Its chemistry offers a high boiling point, stability across a wide temperature range, strong thermal conductivity, and very low toxicity for safer handling—all key traits for dependable performance on the road. Specialty inhibitors maintain an alkaline pH window to further defend system components.

For best results, always follow your heater manufacturer’s recommendations when filling or topping off. Many Aqua‑Hot systems specify a propylene glycol solution in the 35–50% range and advise against exceeding 50%; use distilled or deionized water if dilution is required, and avoid mixing different brands or colors to prevent discoloration or compatibility issues.

Proudly manufactured in Indiana, this formulation reflects the quality standards RV owners expect from American manufacturing. Whether you’re winter camping in the mountains or chasing summer across the plains, you can trust a U.S.-made fluid to safeguard your hydronic system and keep adventures comfortable for years to come.
