Help with aircon connection under car

[middy]

Hope someone may have a drawing or printout of this please?
Under the car (996 c2 2002) on the offside just infront of the rear wheel there is a connection on the low pressure side, it joins front to back of the larger aircon pipe, the joint is pulled together with a single allen bolt. Could anyone tell me what seals the joint, i'm fairly sure it will be o ring(s) but clarification would be good and size of said rings/washers would be most efficacious.

Thanks in anticipation.....

cheers for that, just have to find out what size they are now?? anyone?

Porsche only list as part numbers not sizes, Personally I would play safe and order correct type for the job due to any reaction with fluids etc, as opposed to getting an of the shelf o ring of correct size.

The PET does actually show the sizes of the two 'O' rings. 10.6 x 2 mm and 17 x 2 mm. Brain fade. I can't remember which is LP and which is HP, but it should be obvious. As long as they are compatible with aircon systems, I think you could source them elsewhere, but I doubt they are expensive from Porsche.

I've done the same, the usual problem with aluminium is the corrosion 'parts the joint' So make sure you clean out the joint so its like new and a new correct size o ring is very important, the info provided by Richard 17x2 was spot on, also if you dont get the porshce part, make sure its suitable for air con systems. Most important part is clean clean clean though...
