Peak

.

 

The Peak brand has a 40-year-long history of American ingenuity and entrepreneurship, resulting in quality products at a fair price. Parent company Old World Industries is an independent, family-owned business without “big oil execs,” a “board of directors,” and without any hype—but complete focus on the customer.

Peak antifreeze and coolants are formulated to ensure that automotive engines run in hot and cold temperatures while simultaneously protecting against damaging rust and corrosion. Thermal charge heat transfer fluid are specially-designed refrigerants formulated to provide complete system protection for heavy-duty heat transfer and cooling.
