Another AC Question easy one though

[FLYONWALL9]

I've done a search and perhaps my phrase was too long, but came up with LOADS of threads. None of them seem to address what I'm in need of.

I am looking for the 'hose' which carries the cold air from the AC EVAP box to the passenger cabin. I called our host today and they didn't show this hose also. SO, does anyone have a part number, link, name, any info so that I can get this part on order. This is the last step in my efforts to get more CFM into the car. Once I have the holes fixed I hope to post a HOW-TO thread for the EVAP squirrel cage fan upgrade.

Thanks much!

I had the local ac man source a generic plastic kind. Sold it to me per meter length. They seem to have it by the rolls. It was oversized so a foam layer filler was used to make a good fit to the smallish porsche ducting that is welded in the bulk head. Way cheaper than getting Porsche ori. Sorry but I didn't answer ur question.

Many sizes, lengths, etc. depending on the model and year of your car.

Look on-line for someone who does aftermarket A/C, like Nostalgic Air Parts. They sell 3 inch flexible duct by the foot.

I tried to get one from our local dealer last year.

The part appears to have been discontinued.

Find a used one, or go with the other posts.

Good luck,

Gerry

Three options/ideas for you:

(1) Aircraft Spruce SCAT Tubing. Just measured my spare evap box and the outlet is 3" OD with some stretch (closer to 3-1/8" if duct hose with not stretch a little)

SCAT AIRCRAFT DUCTING from Aircraft Spruce




(2) PVC coupler from Home Depot: $3.50 Neoprene Rubber PVC coupler with stainless compression clamp......discard the stiff compression clamp and reuse the orig hose clamps. The fit is a little tight, only about 1/4" overlap on each end, just enough to secure to the box and vent outlets with little excess. Part number is 3 No Hub Coupling U95-003 Jones Stephens Co. $3.94



Installed



(3) Silicon tubing

Glad I could help. I couldn't agree more with your comments about the forum.

The Porsche part number for the evaporator to cabin flex hose is called "air distribution tube" part number: 91157124001, the hose should cost no more than $9.00 also get two new clamps and a right angle hose tool. Don't fart around with aftermarket parts

The SCAT tubing from Aircraft Spruce will be the equivalent of an OEM replacement vs "farting around with aftermarket" solutions. If you will note from earlier comments contained in this thread, there may be an availability issue on the part from the host and dealership channels.
