Compressor de ar condicionado de jeep bússola

Good morning!, I would like to know if someone can guide me in what happened to me, I broke the compressor of the air and as I had a arrangement I had to buy one I bought the Chinese because the original is $ 28,000 that seemed a bit expensive, in short the question is that it is already the 3rd compressor that I put and breaks it changed all condenser, filter, cigarette valve but I continue to break the first 2 Of days the last one broke when they were loading gas after doing Teste hidráulico com nitrogênio e esvaziamento!
Bem, espero que se alguém tenha uma ideia, eu os apreciaria!
Saudações
