PRO PERFORMANCE RV/MARINE ANTIFREEZE
Pro Marine/RV Antifreeze is a nontoxic, alcohol free, propylene glycol with corrosion inhibitor additive and that is blended with de-ionized water. It is formulated to protect potable water system pipes and marine engine.
Pro Marine/RV Antifreeze is available in three levels of burst protection, -200 degrees F, -100 degrees F, and -50 degrees F.
WHAT IS BURST PROTECTION?
As the temperature drops below the freezing point of the antifreeze, it will crystallize and slush. The antifreeze won’t expand, however, until it reaches the burst point of that specific product.
