Advice in restoration of the heater hose for the warm air passage (sound absorber)

[Maurizio Santini]

Dear Members,

I'm wondering if anyone had successfully restored the heater hose for the warm air passage (sound absorber) that I present you in its anatomy...

One of mine was damaged, but still usable after a proper restoration.

It is not too sophisticated, I think the first step is to search for the hoses, it seems are 2, one inside the other (the black and the kraft paper ones), any advice for finding a company that sell it is very welcomed.

I had read few post about this part in the Registry, and not with detailed photos. Hope it helps and wiil be inspiring. All the best.

Maurizio

I do not think it is an exact fit but it could be modified to be able to use it.

Thanks David for the promptly answer, this is somehow pricey. Having mine rather rust-free my plan is to get a proper kraft paper / aluminium hoses, clean the net and change the insulation with something new. Should be possible.

In case I have to order some meters of the hose, are out there people interested in it?

I didn't realize those hoses were that complex.

There is a ac duct system called space pac the ducts are small and are insolated for sound

If you only need the outer hoses, probably you can find those in a residential air conditioning supplier store.
I checked with Aiexpress "aluminum heater fresh air hose"
And got this answer:

The problem is to find a 100mm diameter hose, most i have seen are smaller in diameter.
There is a chinese supplier for these hoses but they sell wholesale.

Thanks Hugo, I had found this already but I hesitate to contact them as well, but they answered today, I so bought a sample, it will likely be here in few weeks.
