Liquid Line Little Brass Tube?

Hi, I have a strange situation. My AC all of a sudden blew out. There is a little copper tube in the middle of the liquid line, and when I try to charge it the AC fluid leaks out of that little tube. Here are some pictures - it's in between the inner and outer fenders so it's hard to get a good picture of. The red circles show the location. Does anybody know what it's for or why it's there? I got the bar code and put that image up too - it doesn't have the little tube...

Never seen that before. I don't believe it should be there; looks like the piece of copper tube has pierced the line. Road debris? Replace the line and be sure you can pull and hold vacuum before attempting to recharge again.

Well, the vehicle was stopped for 5 or so minutes before it blew, and the line is pretty shielded there. I bought a new one anyway - the problem now is that it has those quick disconnects, and they've been on there for over 10 years. Is there a tool like a snap-ring pliers or something I can use to get them apart? Any suggestions?

It hasn't been on there for 10 years. That's not a factory part as evidenced by the UAC sticker on it.

Springlock connectors have a purpose built disconnect tool that slips in, pushes the garter spring back, and allows you to slide the connector apart.

Looks like that brass thing may have been resting there for a while, and eventually wore a hole through the line.

Springlock tools These or similar tools are also commonly stocked in local parts stores.

Well, the system has been open to the air for awhile so I think I need to change out the accumulator as well - I can depress the springlock quick disconnect, but pulling it apart while depressed is a different question...

I know this is an old thread, but in the interest of future searches, I am going to provide an answer. It appears to be the brass insert portion of the orifice tube. It probably became dislodged from the rest of the orifice tube and the high pressure shot it through the soft aluminum like a projectile.
