"Special Adapter" for Zexel comp.

Kai on Wed September 12, 2007 2:58 PM User is offline

Year: 1996
Make: Audi
Model: cabrio
Engine Size: 2.8L
Refrigerant Type: 134a
Ambient Temp: 90
Country of Origin: United States

I need the “special adapter” to connect the low side hose of my 134a gauge set to the Zexel compressor Type DCW-17B on my Audi I was told it is a R12 connection but the R12 hose will not fit it is slightly to small.

Any idea where to get this?

Thank you,
Kai

I see what I can find out from Valeo in the morning. Might email me reminder in case I get side tracked. Sure it is the low side you are having issues with?

Tim, I am pretty sure it is the Low side I will attach some text from the Audi service manual.


•On the following vehicles, no service connection is provided for the service station on the low-pressure side of the refrigerant circuit. Adapters are required for connecting the service station to the refrigerant circuit of these vehicles.

Service station, connecting with adapter V.A.G /10 to refrigerant circuit
•Unscrew cap from connection with valve - A - (at compressor).
•Attach O-ring - B - to connection (8.9 mm; 1.8 mm).
•Screw adapter V.A.G /10 - C - to connection - B - .
•Install valve opener - D - with appropriate seal in charging hose connection.
•
•Note:
•The type of valve opener - D - and seals required depends on the charging hose used (specific to manufacturer).
•The quick-release coupling adapter is not required for connection on the low-pressure side of Audi vehicles.
•Screw charging hose - E - (to service station) to adapter V.A.G /10.

Not sure why I missed this last night. That is an R134a system. If you want to hook up your R12 gauges/hose you will need these couplers.

Tim, sorry for the confusion

I own 134a gauges/hoses and R12 gauges/hoses
The problem is I can’t get any of them connected to the low side connection which is on the compressor.
It is a special threaded valve on the head of the compressor apparently 8.9mm diameter 1.8mm tread pitch.

There is a picture of it in the Audi Manual do you have an email address that I can send it to.
The forum does not allow to attach a picture.

Thanks again
Kai

You can post images here. Depends on the type of browser you are using as to what icons you see when posting. Not to argue but I had a vendor snap on a R134a coupler this morning on a compressor he had in stock. So it would be nice to see what you have if you can get me an image.

PS: Click on my name and you're email program should open.

Could be the aftermarket compressors come with standard fittings, the original one has a proprietary fitting that needs an adapter.

Tim, I sent the picture to this address [email protected] did you receive it?

Yes and I could not locate any adapter like the one listed with any of my sources. Hate to say it but it my be a dealer item if they even carry it these days. Like I posted before my sources service port using a standard ACME fitting link this one.

How's this?

Audi also says you can remove the low pressure switch and tap in there.

Steve, thanks for posting the image I could not copy and paste the image from the Bentley manual software I ended up taking a picture of the screen and sending it.

Is it possible to remove the low pressure switch and install a T-fitting reinstall the
low pressure switch and add a permanent 134a low side valve for gauge connection?

Chick, thanks for sending that link but I don't see anything that will work apparently the treads on the valve are 8.9mm diameter and 1.8mm pitch.
