What People Are Saying

With the R-134a recharge hose and one can of 134a refrigerant, the air conditioning on my 8.5 years old car is working as good as when the car was brand new. Charging the air conditioning was simple with the directions provided on the recharge hose.

Thank you

My husband sent me to auto parts store for some waterless soap hand cleaner, while he was working on his car. I saw a can of the Spray On Super Seal on your display. Thought it might work on my 1992 Honda Prelude; it has been dripping oil for almost ten years. My husband "big mechanic" tried fixing it several times over the years without success. While he was at work I crawled under the car cleaned the leak area and sprayed the Super Seal. Now it does not leak anymore.

Thank you for a great product.

I was suffering for long time without the A/C in my truck. A friend told me how easy was to recharge my A/C. I recharged my A/C using your Sub-Zero product and it worked wonderfully! I’m so happy now!

I don’t know why I wait to long to do it!!!!

Your product works great! I used your retrofit kit to change my 1990 Corvette to R-134a which has not work for two years.  Your product was readily available at a major auto parts retailer, and the process was easy to understand and follow.

Thanks.

I had trouble getting my air conditioner system to drop below 45 degrees with just r-134a alone, so I evacuated the system and charged it with your R-134a with Sub-Zero Synthetic and the system dropped to 32 degrees.  

Great stuff!!

Dear Sir's. I would like to tell everybody about your A/C Super Seal. I have a 1988 Buick Reatta I parked since new. After all these years I decided to put it back on the road, and to enter it into car show's. From sitting so long, the A/C compressor was leaking oil from all three main O-rings & front seal. To remove the compressor from a Reatta is to say the least, VERY TOUGH!! And time wise Wow!! I used your R-12/R-22 Super Seal. After cleaning the Compressor, guess what? NO LEAKS!!!! Not even the front seal. Unreal!! Thank you for a great product, that Works!!

Used your competitors recharge kit which had parts missing and the fitting leaked.  Note said, "If you are missing any parts or encounter any problems, PLEASE DO NOT RETURN PRODUCT TO THE STORE.  Please call us and we will help resolve your problem."  Got a message and left my number with no return call.  I Used your R-134a QUICK COOL WITH EASY DISPENSER 306. The fitting fitted with no leaks and it filled the system.
