FreezeCar R12 Retrofit & Repair Kit: Stop Leak + Oil + Gas
The Complete Solution for Classic Cars: Convert, Seal, and Fill!
Keeping the AC running in a classic car can be difficult, but FreezeCar makes it easy. This complete kit is designed specifically to revive older R12 systems without the need for expensive mechanical conversions.
We have combined leak sealant, system oil, and high-efficiency hydrocarbon refrigerant into one bottle. Crucially, this kit includes the specific R12-to-R134a adapter, allowing you to connect modern hoses to your classic car instantly.
What’s in the Box?
-
1x All-in-One Bottle (Gas + Leak Stop + Oil)
-
1x Premium Charging Hose
-
1x R12 Retrofit Adapter (Required for connecting to older low-side ports)
Why this is the perfect fix for older cars:
-
Revives Old Seals: Classic cars often have dried-out rubber seals. Our Stop Leak formula rejuvenates these O-rings, creating a tight seal to prevent leaks.
-
Protects the Compressor: Older compressors need protection. Our formula contains premium Oil that mixes with the refrigerant to lubricate the system and reduce wear.
-
Safe Retrofit: Our Hydrocarbon Refrigerant is compatible with R12 systems. It operates at lower pressures than chemical R134a, making it safe for older hoses and components while providing superior cooling.
Simple Application:
-
Adapt: Screw the included R12 Adapter onto your car’s low-pressure service port.
-
Connect: Attach the charging hose to the adapter.
-
Charge: Empty the bottle into the system while the engine and AC are running.
-
Circulate: Run the AC for 15–20 minutes to circulate the oil and sealant.
