Review on 🚗 Ultimate Car Air Conditioning Pipe Cleaning Bottle Flush Kit: Efficiently Maintain A/C System Components for R134a R12 R22 R410a R404a by Elder Unogu

Both brass fittings on the supplied hose are improperly made. The thread is cut at an angle, not parallel to the center of the knurled fitting. This applies to both ends of the supplied hose. It is difficult to start threading the female fitting onto the nipple and once it is threaded the fitting moves forward and "wobbles" on the male threads. Therefore the seal does not fit properly on the 1/4 inch male thread. Improper sealing leaks flammable cleaning solution and is a safety issue. The safety problem is associated with chemical burns to the eyes and skin and an even greater risk of fire. if the solution is near a source of ignition. I have contacted the seller and they are not concerned. They offered me $7 of the original price, but even a cheap replacement tube costs more than double.
