AC refill with leak guard

This AC coolant worked perfectly. I knew I had a small leak and it completely fixed the issue. Attach your own hose and gauge, release pressure if needed.... then fill with the coolant! AC is super cold with only 1 can! Great product. Highly recommend!

Great for recharge

Works great to recharge air conditioning in vehicles. Convenient and easy to use if you have the hoses you need to charge it. Great cold aur after recharge. I recommend for recharge.

Economically priced and includes ability to seal minor leaks. This was perfect to charge a car's A/C system that is 24 years old, and has needed its charge topped off every spring.
