This part is not in the Parts Manual or either version of the Workshop Manual I have. It is a brass piece in-line between the receiver drier and the expansion valve, and appears to either be a check valve or a self closing disconnect.
I am replacing all my hoses and am wondering if I should replace this part, keep it, or toss it.

It also may be a TXV inlet screen. While changing the hoses I would try and determine what it is. But without knowing what it is, why it is there, and how it will effect the performance of the system; I would not just toss it.

I took it down to the local auto AC parts supply house and they told me it is definitely a quick disconnect. They said those have fallen out of favor and recommended getting rid of it.
If that is what it is, I agree; as you will be eliminating another leak point.

It's not a check valve but a quick connect. When they build the car the AC system is charged and ready to go before they install it. There is a seal in one end and a cutter thats also sealed on the other end. When they screw it together the seal gets cut and the system is ready to go.
Easier to install the system this way.
