I had to replace the 4th stage piston/head on my MCH6 knockoff and it took a bit to get the replacement parts. During that time I lost a fitting and I cannot locate it. The fitting I need goes from the 4th stage head to the tube that connects to the condensate, it's a 90 degree fitting that I think is 1/8 FNPT->8mm "Tube". But it might be bspt and AN or something else entirely, I have no clue, I also have no idea how I can figure it out without buying a bunch of fittings and trying them. Here are some pictures of what I need and what I need to reconnect.

Above is the 90 I'm missing (old head before I tore it down)

Here is what it needs to connect, the (new) head to the tube on the bottom.

Closer picture of the threads coming out of the head, 1/8NPT? bspt?

OD of the Tube.

Appreciate any pointers in the right direction or where I can find a replacement 90 or other options to get the compressor back online. I realize these little compressors are junk, however I mostly use it for transferring/boosting TriMix and 100% He, I have a Bauer Capitano as my main compressor.

Thank you
