This is a new old stock E30 A/C line that runs from the compressor to the evaporator.

Part number: 64538391051

Details: I’ve been saving this E30 A/C line for a project that I didn’t get around to using.

It’s a genuine BMW piece that is new old stock. Shows some normal wear from hanging around the garage.

Please make sure this is the exact line you need, as the E30 had a few different compressor options that require different lines.
