Just found a crack on SS tube fitting.

My compressor had a little leak. But was able to fill my 74fc tank from 2300 psi to 4400psi (on tank gauge). Took about 45 mins to do it. I was just looking to check if there is other leaks and found a crack in the coil SS tubing. Kinda scary I just did a 4400 psi fill and it didn't blow. After I saw it I'm a bit worry to fill my tank now. I just got the compressor a few days ago. Less than a week. Would hatsan replace it free since in under warranty or would I have to pay put of pocket for a new tubing?
