Replacing Air Conditioner Drier-Receiver

The factory drier-receiver (part 106647) is made by Hansa and is currently available through many of the regular Ferrari part suppliers. It costs around $165.

The factory drier-receiver is unusual in that it has a #6 female o-ring coupling on one side and a #6 male o-ring coupling on the other. Most conventional drier-receivers have male #6 o-ring couplings on both sides. A conventional drier-receiver costs around $18.

The unusual thing is that the factory used a female-to-female adapter (Part 107402) in order to use the Hansa drier-receiver. If that adapter is removed from the pressure switch union (part 106646), a conventional male-male drier-receiver can be used. This is the best way to go.

Be careful when working on the pressure switch union to remove the female-to-female adapter. The union has a short piece of very thin copper tubing which is easily bent. You might have to double-nut the adapter to get it off; it can be screwed in really tight.

Here are three drier-receivers that work:

Hansa – OEM #6 o-ring male-female. $165.

Singer Controls model 460. #6 o-ring male-female just like OEM. NAPA Autoparts found one for me 5 years ago (last belt change). $28.

Four-Seasons model 33444. #6 o-ring male-male. Needs part 107402 removed. I used this one this belt change. A much better option. Amazon $18.42.

A few points on drier-receivers:

- Common wisdom says you should replace the drier-receiver with a brand new one each time you open up the system.

- Used (!!) factory Hansa drier-receivers are listed on eBay for as much as $500. Don’t buy them! You need a fresh one.

- The purpose of the drier-receiver is to capture moisture in the system which minimizes corrosive acidity of the refrigerant.

- The size of the drier-receiver really doesn’t matter (within reason). As long as it fits, it’ll do its job.

I recognize the template in the background of your photo. I too upgraded the blower fan.
