Review on Joyway Thread Conditioning Refrigeration Charging by Corey Bigglesworth

I work on a car air conditioner and am trying to find an inexpensive set of replacement hoses for an old set of gauges. The price was good, it lacked the quality of materials and workmanship, but at this price, expectations weren't too high. I charged the air conditioning on a car and almost immediately the high pressure hose started to fail. Small bubbles began to appear due to poor quality materials or poor crimping.
