Beat the heat with this value pack of A/C on the GO refrigerant! You get six 255g (9oz) cans of 12a replacement that work great for recharging your vehicle's air conditioning system. Here's the cool part - each can has the equivalent cooling power of 680g of 134a refrigerant, so one can is usually enough for most cars, making this pack perfect for multiple vehicles or keeping some extras on hand. Important note though - these aren't self-sealing cans, so once you attach the hose, you need to use the whole can or you'll lose whatever's left when you disconnect. Always check your vehicle's owner manual first to make sure 12a is compatible with your specific AC system. The cans are straightforward to use if you're comfortable with DIY automotive maintenance, and having six means you're set for a while. Perfect for those who like to handle their own car maintenance or professionals who need a reliable supply. Your summer drives are about to get much more comfortable with a properly charged AC system blowing cold air again!
