KOST® USA Enviro Marine & RV Antifreeze

KOST® USA Enviro Marine & RV Antifreeze is a PROPYLENE GLYCOL BASED ANTIFREEZE used to protect recreational vehicles, boats, summer cottages and swimming pool filters from water freeze up and system bursts down to -50 °F or -100 °F. KOST® USA Enviro Marine & RV Antifreeze is a non-toxic product intended for use in water & plumbing systems that typically go unused during cold winter months.

KOST® USA Enviro Marine & RV Antifreeze is intended to protect water and sewage systems during the off-season in unheated environments such as RVs, boats, and swimming pool filters and supply lines. They may be pre-diluted with up to 70% water to produce a cost effective burst protection fluid for pipes and bowls often left unheated in the winter. RV antifreezes will become slushy fluids at mild freeze conditions and flow will be restricted but, the expansion of the fluid, which causes burst damage, is prevented down to the lower burst temperatures indicated below. The choice of R/V Antifreeze you make should be based on the expected cold temperature your system will encounter during the winter season.

KOST® USA Enviro Marine & RV Antifreeze contains a phosphate corrosion inhibitor designed to protect metal pipes and system components from rust and corrosion during the shut down period. These corrosion inhibitors are not designed for long-term protection. As a result, RV Antifreeze should be flushed out of the system seasonally and should not be reused.
