Not sure which FreezeCap™ fits your vehicle?

R-134a covers most 1994–2012 vehicles. R-1234yf covers 2021 and newer. 2013–2020 is the mixed transition window: check your under-hood sticker, owner's manual, or VIN. Two models, 95%+ of vehicles on the road today.

FreezeCap™

The patented A/C cap that ends the recharge cycle.

Engineered and assembled in Florida. Shipped from Texas. Built for vehicle owners who'd rather fix it once than refill it monthly.
