Review on 🧲 FOUR UNCLES IRONCUBE AC Flush Kit - Ultimate A/C System Cleaning Tool Set for Auto Cars - R134a R12 R22 R410a R404a Compatible - Includes 3.5 ft Hose with American Interface by Paul Lee

First I used this to flush the injectors through the rail. I only needed the basic components that come with this kit. The stainless steel tank was a quality product as were most of the other items supplied. They were kind enough to provide a male quick connector for US use. Obviously, this product does NOT use standard tapered pipe threads, so plan on using plenty of Teflon tape to seal the fittings. Everything worked fine, but I noticed that the gauge read 10psi less than my test gauges.
