Long story short I was installing the grimmspeed master cylinder brace and messed up.
Instead of removing the 10mm ac line bracket bolt, I loosened the AC line and it discharged my r134a refrigerant.
I then went to retighten it and i could still hear it hissing, continued to tighten and then I thought I stripped it. There are 2 crush washers so I hope it was that.
Does anyone know what part this is in case I need to replace it. It's the box that AC lines go to (coming from above tmic) and from (towards radiator) next to the drivers strut tower wall.
Just want to be clear, my apologies for being a noob
