What is this coolant line called?

[NRamsey]

Good afternoon! Does anyone know what the name of the coolant line is, outlined in red below? I'm trying to replace its o-rings.

The line seems to pass through and exit on the driver's side.

After visiting the parts department at a local dealer, I learned I'm looking at a Water Outlet Tube, pn 68139108AA. The tube is connected to the Torque Converter Cooler, pn 68139111AA and costs about $400! Also, they don't show a replacement o-ring for it - the dealer says it has a pressed in seal that only comes with a new tube. Ugh!

You might visit a hydraulic hose repair shop, they may be able to make a replacement for you .
It’s a stretch but worth trying.

Kind of a mostly-permanent solution, but worked great when I had a thermostat housing that refused to seal against the intake manifold. Used it as both the 'gasket' material AND globbed it all around the housing as well. No more leaks. LOL. So it's good to at least 16 PSI. Probably considerably more.

The dealer had a similar idea - he suggested a specialty seal shop here in Albuquerque. They were able to recommend an o-ring which, so far, is holding! I'm sorry to say I don't have the dimensions, but the part number is "2-210HS70".

UPDATE - The new o-ring (which is green) sealed for a while, but eventually started leaking. I removed it and don't see anything wrong with it - maybe it shrunk? I went back to the hydraulic shop and they sold me an orange silicone version, pn 2-210S604. I also applied black RTV to the inner diameter. I'll update this post if I have to do anything else to it.
