This is for an extremely rare NOS original equipment Genuine Mercedes W123 a/c drier accumulator made by Hansa of Germany. This drier fits all W123's and works for any refrigerant including R12. This is a factory original production line part as indicated by the special rubberized undercoating on the lower half. When this is mounted the bottom half sits outside of engine bay while the a/c lines connect inside the engine bay. Only genuine OE Mercedes driers were finished like this.On your W123 and you want a genuine Mercedes drier made in Germany then this is likely the last one in existence. R12 FYI : There is so much misinformation about using R12 freon/refrigerant. Few people realize that the EPA specifically outlined an exception in the regulations for "DIY" car owners. They actually use the term "DIY" in the law.
The EPA's focus was only to stop production of R12. There's nothing shady or risky about it. It's everywhere while supplies last. Luckily it's not consumed like gasoline. A/C systems rarely need to be fully recharged once they are sealed.
My advice, put R12 in your R12 system and be done with it. Nothing else comes close and it requires zero modifications. You can do all sorts of mods with lots of labor trying to make an R12 system work just OK with R134a but there's no point in going through all of that time and expense to get "almost as good" when you can just put in R12 as designed. If there's a problem let me know and I'll work with you.OFFERS: Depending on the item I can sometimes adjust a little. If you have any questions just ASK. An example is having a U.
