R12 AC Restoration Kit (Stop Leak + Refill + Adapter)
Bring the chill back to your classic ride—and keep it there.
Owning a vehicle manufactured before 1993 often means dealing with two problems: an AC system that has leaked out over the years, and incompatible R12 service ports. The Freeze Car Restoration Kit solves both problems in one box.
We have combined our premium refrigerant with our powerful Stop Leak conditioner and the necessary hardware to make this the easiest “Drop-in” solution on the market.
Why this kit is essential for older cars:
-
It Stops the Leaks: In older cars, rubber seals and O-rings dry out and shrink, causing gas to escape. Just refilling the gas isn’t enough—it will leak out again. This kit includes a dedicated can of Freeze Car Stop Leak to recondition and swell those seals, creating a tight system.
-
It Connects Perfectly: Modern hoses don’t fit classic cars. We include the specific R12 Retrofit Adapter (Screw-on to Quick-Connect) so you can hook up our hose to your car’s low-pressure port instantly. No tools required.
-
It Replaces R12 Safely: Our hydrocarbon formula is non-corrosive and operates at lower pressures than modern gas, preserving your vintage compressor while blowing ice-cold air.
What’s in the Box?
-
1 x Can of FreezeCar Universal Refrigerant: High-performance, eco-friendly cooling gas.
-
1 x Can of FreezeCar Stop Leak (Rubber): To seal leaks and lubricate the system.
-
1 x Premium DIY Hose: With an integrated pressure gauge to measure levels accurately.
-
1 x R12 Retrofit Adapter: Converts your old R12 screw-port to a modern quick-connect port.
How to use:
-
Screw the R12 Adapter onto your car’s low-pressure port.
-
Connect the hose and fill the Stop Leak can first to condition the seals.
-
Switch cans and fill the Refrigerant until the gauge is in the blue zone.
-
Enjoy a leak-free, ice-cold classic car!
Note: This kit is designed for systems that are low on gas or empty due to minor rubber leaks. It cannot repair broken metal components.
